Abstract — In this paper, we evaluate and compare the SER performance of few quasi-orthogonal space-time block codes (QOSTBCs) with three time slots for two transmit antennas. The decoding used is ML and fading channel is Rician. We observe that codes proposed in [14] performs better than the codes of [6].
