Performance of Variable-Power Adaptive Modulation With Space-Time Coding and Imperfect CSI in MIMO Systems

The performance analysis of multi-input-multi-output (MIMO) systems with M-ary quadrature amplitude modulation (MQAM) and a space-time block code (STBC) over flat Rayleigh fading channels for imperfect channel state information (CSI) is presented. In this paper, the optimum fading gain switching thr...
