Performance analysis of combined transmit SC/receive MRC for MIMO systems in correlated fading channels

Guangqiu Li

Abstract

A diversity system with combined antenna selection at the transmitter with maximum-ratio combining(MRC)at the receiver for multiple-input-multiple-output(MIMO)systems in correlated Rayleigh fading channels is investigated in this paper.By using the moment generating function-based analysis approach,closed-form solutions to the average symbol error probability(SEP) of several M-ary modulation schemes(including M-ary phase shift keying(MPSK),M-ary quadrature amplitude modulation(MQAM),M-ary pulse amplitude modulation(MPAM))for MIMO systems with coherent detection are derived.Numerical results illustrate the effect of correlation and antenna configurations on the average SEP of several M-ary digital modulation schemes for MIMO systems.
