TLDR
In this article, a coherent binary phase shift keying (BPSK) modulation scheme operated in the asynchronous mode is presented, where a standard Gaussian approximation is used to derive approximated error probabilities, P/sub e/, in simple form.Abstract:
The model uses a coherent binary phase shift keying (BPSK) modulation scheme operated in the asynchronous mode. For ease of interpretation of results, raised cosine spectra for filters is assumed. A standard Gaussian approximation is used to derive approximated error probabilities, P/sub e/, in simple form. The effect of imperfect despreading synchronization is shown.read more

Performance of asynchronous orthogonal multicarrier CDMA system in frequency selective fading channel
Xiang Gui,Tung-Sang Ng +1 more
TL;DR: An asynchronous multicarrier (MC) direct-sequence (DS) code-division multiple-access (CDMA) scheme for the uplink of the mobile communication system operating in a frequency selective fading channel performs better than that of the conventional DS-CDMA system and another MC-DS- CDMA system.

A System Level Energy Model and Energy-Quality Evaluation for Integrated Transceiver Front-Ends
TL;DR: For a given communication quality specification, it is shown that the energy consumption of a wireless communication front-end can be scaled down by adjusting parameters such as the pulse shaping filter roll-off factor, constellation size, symbol rate, number of users in the cell, and signal center frequency.

Louay Jalloul,J.M. Holtzman +1 more
TL;DR: In this paper, the performance of a DS/CDMA system using M-ary orthogonal modulation with non-coherent demodulation is evaluated in a multipath fading channel and an approximation to the bit error probability is given which depends only on the first and second-order moments of the multipath energies.

A simple and accurate method of probability of bit error analysis for asynchronous band-limited DS-CDMA systems

A novel approach for estimating multi-user interference in impulse radio UWB networks: the pulse collision model
TL;DR: A novel analytical expression for the average BER is provided based on the observation that interference in IR is provoked by collisions occurring between pulses belonging to different transmissions, which shows improved accuracy in estimating BER.

Error Probabilities for Binary Direct-Sequence Spread-Spectrum Communications with Random Signature Sequences
