| Abstract: | The procedure of MIMO-STOBC downlink receiver was deeply studied, and the fundamentals of ML decode were described, After comparing and analyzing some algorithms, utilizing the statistic characteristics and approximate-relation of received signals, considering the realization complexity and computation, utilizing code division, an simplified MIMO-STOBC downlink receiver algorithm with high practical value was proposed. The simulation results prove that the algorithm has excellent performance, especially in high SNR. |
