A Novel Cyclic STBC Encoding and Decoding Scheme In MIMO CDMA System
MIMO CDMA系统中一种新的循环空时分组编译码方法

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.
