协作分集技术是为了解决无线通信系统中MIMO技术在移动终端的多天线制约问题而提出来的,协作分集可以使得具有单天线的用户共享其它用户的天线,从而形成虚拟的多天线系统,从而为MIMO技术的实用化提供了一条可行的道路。文中先讲述了协作分集的概念和协作分集的种类,然后详细分析了解码协作模型的协作过程,给出了其在不同情况下的误码率,最后通过仿真并观察其误码率,证明其拥有很好的性能。
Cooperative diversity technology is proposed to solve the multi-antenna constrained problem of MIMO technology in mobile terminals in wireless communication systems. Cooperative diversity can make users with single antenna share the antennas of other users to form a virtual multi-antenna system. The practical application of MIMO technology provides a viable road. This paper firstly introduces the concept of cooperative diversity and the types of cooperative diversity, and then analyzes the cooperation process of the decoding cooperation model in detail, and gives the BER under different conditions. Finally, we simulate and observe the bit error rate Have a good performance.
