Symbol Error Performance Analysis and Comparison Between Alamouti and MRRC Diversity Combining Scheme for Wireless Communication
Keywords:Alamouti scheme, M-PSK, M-QAM, MRRC, Symbol error probability.
The symbol error performance of a wireless communication system is analyzed using diversity combining scheme in Rayleigh fading channels. The performance of the system is compared using Alamouti scheme and maximal-ratio receiver combining (MRRC) scheme. The performance results of the system are evaluated by numerical computation and by simulation using MATLAB. A detailed analysis and exact (closed-form) expressions of the probability of error of the wireless communication systems in Rayleigh fading channels are provided for both M-ary phase-shift keying (M-PSK) and M-ary quadrature amplitude modulation (M-QAM) schemes. Monte Carlo simulation shows exact match with the theoretical results.
Keywords: Alamouti scheme; M-PSK; M-QAM; MRRC; Symbol error probability (SEP).
