Abstract A space-time and multi-path diversity combining algorithm is presented in STBC block transmission system with two transmit antennas and one receive antenna. The primary detection is carried out by STBC-based Single Carrier Frequency Domain Equalizer (STBC-SC-FDE), then the multi-path components in the received signal are separated by the initial solution and channel state information. After all the multi-path components are processed by the STBC combining algorithm, the output branches are combined together using Maximal Ratio Combining (MRC) algorithm in the space-time two dimensional RAKE receiver. The new scheme can achieve transmit and multi-path diversity under low computational complexity, and the performance is evaluated by Monte Carlo simulations.
