摘　　要：采用群多用户检测和STBC解码的线性检测相结合的两级检测技术没计出STBC系统多用户接收机, 解决了码分多址(CDMA)系统空时码研究领域的关键技术.仿真结果表明它能消除绝大部分多用户干扰,证明 该接收机良好的性能.Multi-user receivers have recently become the key technique for CDMA systems with Space-time Coding. A novel multi-user receiver over the additive white Gaussian CDMA channel is discussed. Linear detection for STBC decoding associated with group detection techniques has been considered. This solved the key technique in the field of CDMA systems w:ith space-time coding. Simulation results show the receiver can resist the most multi-user interferences and perform well.
