Abstract A novel space-time block encoding and decoding method in MIMO CDMA system is proposed in this paper. It is called Cyclic Space-Time Block Code (C-STBC). The input data stream is circularly encoded in block, and then the encoded data streams are transmitted through different antenna by multiplying different spread code respectively. The proposed C-STBC scheme in CDMA system can achieve full coding rate and full diversity gain but the decoding method is simple as the conventional STBC. Simulation results show that the proposed C-STBC is superior to the conventional STBC.
