In this paper, we propose a modified quasi-orthogonal space-time block code that the decoder decouples the symbol detection problem into not pairs of transmitted symbols but each symbol. And then, it is applied to cooperative communication systems with 4 transmit antennas. Simulation results present the BER performances in cases of amplify-and-forward and decode-and-forward.
