摘要 为了解决无线通信系统中多输入多输出技术在移动终端的多天线制约问题,一种新的分集技术-协作分集技术被提出。它使得在多用户环境中,具有单根天线的移动台可以共享彼此的天线而产生一个虚拟MIMO系统,从而获得分集增益。文中介绍了协作分集的基本概念、编码协作机制,分析了编码协作机制下成对误差概率、误码率、误块率的性能,讨论了今后的研究方向。 The multiple-input multiple-output requires more than one antenna at the mobile terminal. Unfortunately, this is impractical in wireless cellular system due to size, cost andhardware limitations. To solve the problem, a new diversity technique called cooperation diversity is proposed. The cooperation diversity allows single-antenna mobiles in a multi-user scenario to share their antennas in a manner that creates a virtual MIMO system. The conception and coded cooperation are presented in this paper. And the paper also analyzes the performance of coded cooperation and discusses some issues that remain to be addressed.
