A space-time block coding based on the maximum likelihood decoding criterion

As one of the solutions of the space-time processing, multiple inputs and multiple outputs system can increase the capacity of wireless communication system and improve the system performance of bit error rate, but it takes higher cost. We introduced a kind of space-time coding method through spatial diversity technology. This method adopts simple maximum likelihood decoding rule and can obtain full diversity. We also give the performance analysis of 2X1, 1X1 and 1X2 systems through numerical simulations.
