Performance Analysis of MIMO MRC with Channel Estimation Error

Guangqiu Li

Abstract

By using Wishart random matrix theory and the moment generating function-based analysis approach,the exact closed-form expressions for the average symbol error rate (SER) of rectangular M-ary quadrature amplitude modulation (MQAM) multiple-input multiple-output (MIMO) maximal-ratio combining (MRC) systems with channel estimation error in independent and identically distributed Rayleigh fading channels are derived. Numerical results show the effects of channel estimation error and the number of transmit and receive antennas on the average SER of MIMO MRC systems with rectangular MQAM.
