PERFORMANCE OF MQAM WITH DUAL MRC DIVERSITY RECEPTION OVER CORRELATED NAKAGAMI – m FADING CHANNELS
Error rate performance of coherent square M – ary quadrature amplitude modulation (CSMQAM) over fading channels under diversity reception is obtained and analyzed. The diversity combining technique considered is maximal ratio combining (MRC). The fading channels are modeled as frequency nonselective slow Nakagami – m fading channels corrupted by additive white Gaussian noise (AWGN). The exact a...
متن کاملAnalysis and Simulation of MRC Diversity Reception in Correlated Composite Nakagami-Lognormal Fading Channels
The physical meaning of the composite Nakagami-lognormal fading model is not well understood by many researchers using the model. The signal power transfer and transform at the interface between the global lognormal shadowing sub-channels and the local Nakagami multipath sub-channels in the presence of correlation between these diversity sub-channels is rather complex. This is the main reason w...
متن کاملPerformance analysis of adaptive MMSE reception for DS-CDMA in flat Nakagami fading channels
An efficient method is derived in this paper to obviate the integral involved in the performance analysis of the minimum mean square error (MMSE) detector for direct-sequence code-division multiple-access (DS/CDMA) systems in fading environments. The new method is shown to significantly reduce the necessary computational load for the performance analysis of the MMSE detector. We then examine th...
متن کاملPerformance of multiuser diversity reception in Rayleigh fading CDMA channels
Error probability of an adaptive multiuser diversity receiver is evaluated in terms of channel fading rate and the number of code-division multiple access users. Fading-induced performance loss, which leads to error probability floor, is established for the proposed coherent combining scheme and compared to that of differentially coherent receiver with equal-gain combining.
متن کاملPerformance Analysis of Coherent TCM Systems with Diversity Reception in Slow Rayleigh Fading
Coherent trellis-coded modulation (TCM) systems employing diversity combining are analyzed. Three different kinds of combining are considered: maximal ratio, equal gain, and selection combining (SC). First, the cutoff rate parameter is derived for equal gain combining (EGC) and SC assuming transmission over a fully interleaved channel with flat slow Rayleigh fading, which permits comparison wit...
