TLDR
A closed-form expression for the Shannon capacity of MIMO systems is derived using STBC under independent and quasi-static flat Rayleigh fading channels, thereby avoiding the need for numerical integration or Monte Carlo simulation.Abstract:
Space-time block coding (STBC) is a powerful transmit diversity scheme for multiple antenna systems. A closed-form expression for the Shannon capacity of MIMO systems is derived using STBC under independent and quasi-static flat Rayleigh fading channels. The Shannon capacity of STBC over such channels is expressed as a finite sum of functions that are easy to evaluate, thereby avoiding the need for numerical integration or Monte Carlo simulation.read more

Shannon Capacity and Symbol Error Rate of Space-Time Block Codes in MIMO Rayleigh Channels With Channel estimation Error
TL;DR: This paper analyzes the impact of channel estimation error on the ergodic capacity and symbol error rate (SER) for space-time block coded multiple-input multiple-output (MIMO) systems and derives a closed-form capacity expression over MIMO Rayleigh channels withChannel estimation error.

Effective Throughput Analysis of α - η - κ - μ Fading Channels
TL;DR: It is found that the effective throughput improves with the increase of channel nonlinearity and number of multipath clusters, and the high-SNR slope is only dependent on the channel non linearity and the number of multiclass clusters present in the physical channel.
Analysis of OFDMA resource allocation with limited feedback
TL;DR: The spectral efficiency analysis of multiuser OFDMA with imperfect feedback path, multiple antenna methods and relaying methods is a particular focus and shows that the analytical results with idealized IID fading assumption are close to those obtained via simulations in a practical frequency selective channel when RBs are selected properly.

Capacity Analysis for Path Selection Based DF MIMO-OSTBC Cooperative Wireless Systems
TL;DR: It is observed that while the availability of full CSI at the source generally leads to a higher capacity, its performance gain over the scenario with partial CSI is only marginal when either the source-destination or source-relay link is relatively strong.

A simple transmit diversity technique for wireless communications
TL;DR: This paper presents a simple two-branch transmit diversity scheme that provides the same diversity order as maximal-ratio receiver combining (MRRC) with one transmit antenna, and two receive antennas.

Capacity of Rayleigh fading channels under different adaptive transmission and diversity-combining techniques
TL;DR: In this paper, the Shannon capacity of adaptive transmission techniques in conjunction with diversity-combining was studied. And the authors obtained closed-form solutions for the Rayleigh fading channel capacity under three adaptive policies: optimal power and rate adaptation, constant power with optimal rate adaptation and channel inversion with fixed rate.

Space-time block codes: a maximum SNR approach
Girish Ganesan,Petre Stoica +1 more
TL;DR: This work casts space-time codes in an optimal signal-to-noise ratio (SNR) framework and shows that they achieve the maximum SNR and, in fact, they correspond to a generalized maximal ratio combiner.
