摘　　要：协同分集是当今一种流行的无线通信技术,本文研究了协同分集技术在CDMA系统中的两种具体实现方案——译码前传和放大前传,并重点分析了MMSE多用户检测器在协同网络中的应用。表明MMSE多用户检测器在协同网络中依然可以带来额外的分集增益,降低误码率,有效的抵制多址干扰。Cooperative diversity is a popular wireless technology. The article studies two kind of concrete strategies in the cooperative CDMA system Amplify and Forward（AF）, Decode and Forward （DF）, then the passage analyses the application of MMSE MUD in the cooperative network. It is illustrated that, through using MMSE detection in the cooperative network, cooperation is beneficial in terms of introducing additional diversity gain, ensuring a low bit error rate and mitigate Multiple Access Interference effectively.
