TL;DR: This paper uses a novel gamma approximation to log- normal distribution to evaluate the performance of a PLC system over log-normal fading channel under Nakagami-m distributed additive background noise assuming binary phase shift keying modulation scheme.
Abstract: Power line communication (PLC) utilizes power lines for the purpose of electronic data transmission. The performance of a PLC system is significantly affected by the additive and multiplicative power line noises; the additive noises are of two types, namely background noise and impulsive noise. Whereas, the multiplicative PLC noise leads to fading in the received signal strength. In this paper, we evaluate the performance of a PLC system over log-normal fading channel under Nakagami-m distributed additive background noise assuming binary phase shift keying modulation scheme. The analysis involving log-normal fading is very complicated. Hence we use a novel gamma approximation to log-normal distribution for our analysis. We evaluate the probability density function of the decision variable. A closed-form expression of the analytical average bit error rate of the considered system is derived. We also compute the diversity order of the considered PLC system. The validity of the derived analytical expressions is closely verified by the simulation results.

TL;DR: In this article, the bit error rate (BER) performance of a free space optical (FSO) communication system was evaluated in the presence of amplified spontaneous emission (ASE) noise under weak, moderate to strong, and very strong atmospheric turbulence regimes and PEs.
Abstract: The performance of a free space optical (FSO) communication system is significantly affected by various atmospheric turbulence conditions and pointing errors (PEs) apart from the additive noise, which is assumed to be Gaussian Optical pre-amplifiers are an essential component of FSO systems for improving the receiver sensitivity However, optical pre-amplification results in amplified spontaneous emission (ASE), which dominates the receiver thermal and shot noises The square law photodetection process at the receiver in a FSO system necessitates the consideration of chi-square statistics for the decision variable contrary to the Gaussian approximation that is widely used in the literature In this paper, we evaluate the bit error rate (BER) performance of a FSO system assuming non-return-to-zero on–off keying modulation in the presence of ASE noise under weak, moderate to strong, and very strong atmospheric turbulence regimes and PEs We also derive asymptotic BER expressions for the considered FSO system for large values of the signal-to-noise ratio in terms of simple elementary functions Further insight into the system is provided by performing a diversity analysis

TL;DR: In this paper, a unified methodology which takes into account the advantages and disadvantages of different Power Line Communication (PLC) technologies suitable for Smart Metering deployment is presented. But this methodology is not suitable for large-scale deployment.
Abstract: The paper describes a unified methodology which takes into account the advantages and disadvantages of different Power Line Communication (PLC) technologies suitable for Smart Metering deployment. The methodology should provide a detailed evaluation of PLC technologies based on a clear definition of the different parameters and their measurement. Based on this methodology, we should be able to provide a comparison of the selected technologies and the methodology should also provide data for the design of a telecommunication infrastructure for Smart Metering/Smart Grids. In this paper and based on this methodology, we also present the performance tests carried out in laboratory environment on low voltage and in on-field conditions on medium voltage.DOI: http://dx.doi.org/10.5755/j01.eie.24.3.20983

TL;DR: A general framework for the coexistence of broadband satellite system and terrestrial cellular networks with distinct geometry, configuration, and channel characteristics is defined, and closed-form expression for the outage probability of the cognitive cellular user is derived.
Abstract: This paper investigates the outage performance of cognitive broadband satellite systems and terrestrial cellular network in millimeter wave (nunWave) scenario. Considering the state-of-art standard recommendations and nun Wave propagation model, we first define a general framework for the coexistence of broadband satellite system and terrestrial cellular networks with distinct geometry, configuration, and channel characteristics. Then, by employing a interference temperature constraint at the fixed satellite service (FSS) receiver to limit the interference below an acceptable level, closed-form expression for the outage probability (OP) of the cognitive cellular user is derived, which is general and applicable to various channel parameters and geometric scenarios. Eventually, simulation results are carried out to verify the theoretical derivations, and shows the impact of key system parameters on the performance of the terrestrial cellular user with the coexistence of FSS.

TL;DR: It is analytically prove that MIMO doubles the Diversity order with different combining schemes while the diversity order of a system under Nakagami-like noise is only half the diversity orders that would have been obtained under Gaussian noise.
Abstract: This work targets a comprehensive understanding of the impact of the serial-relaying and multiple-input-multiple-output (MIMO) fading mitigation techniques on the performance of indoor power line communication (PLC) systems. While these techniques were studied extensively under additive Gaussian noise, we aim at highlighting the implications of Nakagami-like noise on the achievable performance levels. The author derive approximate closed-form expressions for the bit error rate (BER) under Rayleigh fading and Nakagami-m background noise where the obtained approximations are very close to the exact BERs. The derived expressions are useful for evaluating the achievable diversity orders and for relating the BER to the main parameters of the PLC system in a direct and intuitive way. In this context, we analytically prove that MIMO doubles the diversity order with different combining schemes while the diversity order of a system under Nakagami-like noise is only half the diversity order that would have been obtained under Gaussian noise. The author also shows that multi-hop relaying does not enhance the diversity order.

TL;DR: This letter provides the performance evaluation of a PLC system assuming DBPSK modulation under the combined effect of Nakagami-m background noise and impulsive noise and utilizes a simple, yet accurate approximation available in literature to derive the probability density function of the sum of two NakagAMI-m random variables.
Abstract: Power line communication (PLC) utilizes power lines for the purpose of electronic data transmission. Differential binary phase shift keying (DBPSK) is a popular modulation scheme proposed in the PLC standards like G3, PRIME, and IEEE P1901.2. This letter provides the performance evaluation of a PLC system assuming DBPSK modulation under the combined effect of Nakagami- $m$ background noise and impulsive noise. We utilize a simple, yet accurate approximation available in literature to derive the probability density function of the sum of two Nakagami- $m$ random variables. Closed-form expressions of the analytical average bit error rate and the outage probability of the system are derived. Validity of the derived analytical expressions is closely verified by simulated results.

TL;DR: An approach of efficient resource allocation is introduced in order to maximise the throughput and achieve tolerable bit error rate of the power line system, by adapting power transmitted in each cycle, under additive Middleton class A impulsive noise (MCAIN).
Abstract: Power lines render very harsh and hostile environment for electronic data communication. The key characteristics of the power line channel are time varying nature, frequency selective attenuation and presence of impulsive noise because of random switching of power appliances. The impulsive nature of the additive noise has been ignored so far in the literature for resource allocation in power line communication system because this assumption results in intractable solutions. In this study, an approach of efficient resource allocation is introduced in order to maximise the throughput and achieve tolerable bit error rate of the power line system, by adapting power transmitted in each cycle, under additive Middleton class A impulsive noise (MCAIN). The proposed resource allocation technique utilises sub-channel ordering to obtain a higher throughput; and provides improvement as compared to the existing zero forcing based resource allocation technique under additive MCAIN.

TL;DR: The condition for optimum detection of quadrature phase shift keying signals over Nakagami-m distributed additive background noise in power line communication system is derived and the proposed receiver performs significantly better than the existing suboptimal receiver.
Abstract: Power line communications is the use of power lines for the dual purpose of power transmission and data transmission. It is an emerging field of communication for the home area network of smart grid. Power line noise, namely background noise and impulsive noise, significantly affects the performance of power line communication systems. In this paper, we derive the condition for optimum detection of quadrature phase shift keying signals over Nakagami-m distributed additive background noise in power line communication system. The probability density function and the cumulative distribution function of the decision variables for the real part and imaginary part of the background noise are derived. We use the copula approach to model the dependence among the decision variables. The analytical average symbol error rate and average bit error rate of the PLC system is numerically computed. Simulations suggest that the proposed receiver performs significantly better than the existing suboptimal receiver.

TL;DR: This paper provides the performance analysis of a PLC system over Rician fading channel under Nakagami-m distributed additive background noise assuming binary phase shift keying modulation scheme and derives the probability density function of the decision variable and the instantaneous signal-to- noise ratio (SNR).
Abstract: Power line communication (PLC) deals with the transmission of data through the use of power lines. It is an emerging field of communication for the home area network of smart grid. The presence of the additive and multiplicative power line noises significantly affects the performance of PLC systems. There are two types of additive noises in PLC systems, namely background noise and impulsive noise. The multiplicative PLC noise results in fading in the received signal strength. The Rician fading model has been experimentally found to be applicable to the PLC systems and has been widely used in conventional and current literature on PLC. In this paper, we provide the performance analysis of a PLC system over Rician fading channel under Nakagami-m distributed additive background noise assuming binary phase shift keying modulation scheme. We derive the probability density function of the decision variable and the instantaneous signal-to- noise ratio (SNR). A closed-form expression of the outage probability of the considered system is obtained. The validity of the derived analytical expressions is closely verified by the simulated results.

TL;DR: In this article, the root-mean square delay spread (RMS-DS), the average channel gain, and the channel capacity of Brazilian in-home and lowvoltage electric energy distribution networks as a data communication medium were analyzed.
Abstract: This contribution outlines a statistical characterization of Brazilian in-home and low-voltage electric energy distribution networks as a data communication medium. The discussions are based on estimated channels obtained in a measurement campaign carried out in several apartments whose size ranges from 50 up to 90 square meters. The parameters considered for this analysis is the root-mean square delay spread (RMS-DS), the average channel gain, and the channel capacity. For the sake of comparison with electric networks in US, the frequency band ranging from 1.705 up to 30 MHz was set. The reported analysis shows that the RMS-DS can be modeled as a log-normal variable in only 33.33% of the cases and the average channel gain does not follow a log-normal distribution, the average channel gain is lower in Brazil than in US and the inter-symbol interference is quite similar in both US and Brazil.
