Abstract :
In this paper, we present a scheme for optimal power allocation of MIMO systems with hybrid SM and STBC employing ZF and SIC detectors to minimize average BER. It´s shown from analysis and numerical results that the optimal power allocation depends on many different factors such as modulation, diversity order, coding rate and the number of antennas transmitting each data stream, etc., where equal power allocation is only optimal in some special cases
