Abstract: This paper studies on the application about a new type BLAST——Random Layered Space-Time（RLST） which presents in this article used in the TD-LTE system.After the comparison on the result of theory and the simulation，it compares the performance of the RLST with the general V-BLAST in the CDMA structure，and at the same time it compares the performance of the receiver which is using the RLST in the different channels.At last，it proves the superiority of using RLST and the exactness of the turbo multiuser receiving algorithm which is basing on the RLST by the theory comparison and the simulation.

摘要： 采用一种新型的分层空时编码——随机分层空时编码（RLST），针对其在TD-LTE系统中的应用进行了研究，通过对理论的分析，进行了RLST和V-BLAST在CDMA结构下的性能比较，并对应用RLST结构的接收机在不同信道环境下的性能比较，最后通过仿真结果表明了使用RLST结构的优越性，也证明了针对RLST结构提出的迭代多用户接收算法的正确性。
