Abstract

In this paper we present a comprehensive analysis of multiple-input multiple-output (MIMO) transmit maximal ratio transmission (MRT) and receive maximal ratio combining (MRC) systems with rate adaptive modulation. We investigate the performance of MIMO MRT-MRC systems with data rate adaptation. We derive expressions for the average BER and spectral efficiency for the non-delayed feedback case. Furthermore, we analyze the effect of delayed feedback on the BER performance and an exact formula is presented. Numerical results are given to illustrate the sensitivity of the main performance to the error caused by time-delayed feedback.
