Symbol Error Probability Analysis of M-ary QAM Using Hybrid Diversity Technique in Rayleigh Fading Channel
نویسنده
چکیده
In this Paper the exact expressions for the Symbol Error Probability (SEP) of Hybrid Selection/Maximal Ratio Combining wireless systems for M-ary QAM are derived and analyzed in multipath fading environment. Independent Rayleigh fading diversity branch is assumed for analysis with equal Signal-to-Noise Ratio averaged over the fading channels and coherent detection of M-ary Quadrature amplitude modulation (MQAM) is considered. Virtual branch technique, which transforms the ordered physical branches, which are dependent into independent, and identically distributed virtual branches is used, thereby permitting the derivation of exact SEP expressions.

Symbol Error Probability for Generalized Selection Combining Reception of M-qam
In this paper, symbol error probability (SEP) for generalized selection combining (GSC) reception of M-ary quadrature amplitude modulation (M-QAM) signals in a block frequency-flat Rayleigh fading channel is considered. The paper presents a closed-form approximate SEP expression for GSC reception of M-QAM signals in the fading channel. The SEP expression is explicit and simulation results valid...

This paper extends previous works [11[21[3] in matched filter bounds and provides a theoretical calculation of detection probability of q-ary QAM signals transmitted over the diversity reception and multipath fading IS1 channels. The matched filter bounds represent the best attainable detection performance of a particular system, which may or may not be realized with a practical system. While a...
