| 摘 要： | 本文利用MATLAB软件仿真平台,比较研究了TD-SCDMA系统中基于传统的Schur算法和block-Schur两种联合检测算法。对两种算法在三种瑞利衰落信道模型中最差的CASE3情况下进行了性能比较,并对两种算法在不同用户数下的运算量做了仿真分析,仿真结果表明两种算法都能达到比较好的误码性能,在3GPP协议规定处,两种算法都能被系统所接受,并且block-Schur算法比传统的Schur算法具有更好的误码性能,运算效率高。

| Abstract: | In this paper,by using MATLAB software simulation platform,the performance comparison of block-Schur algorithm and conventional Schur algorithm via worst CASE3 rayleigh fading channel is given and the simulation analysis for two algorithms is carried out with different users.The simulation result shows that both of the two algorithms can reach better BER(bit error rate) performance and that the block-Schur algorithm has better BER performance and higher operation efficiency than the conventional Schur algor... |
