摘要
MIMO系统中,编码与空间分集的结合可以在无线通信链路中实现可靠高速率。针对V-BLAST结构提出了检测算法的研究与分析。通过MATLAB进行无干扰消除、理想干扰消除及非理想干扰消除不同情况的参数设置,分别对ZF与MMSE算法进行性能对比,由仿真结果可知:在ZF与MMSE算法中,干扰消除均可以提高输出信号的信噪比,而MMSE检测算法性能更优。
In MIMO systems,the combination of coding and spatial diversity can achieve reliable and high rate in wireless communication links.The research and analysis of detection algorithm for V-BLAST structure are presented.The performance of ZF algorithm and MMSE algorithm are compared by MATLAB in different situations of no interference cancellation,ideal interference cancellation and non-ideal interference cancellation.The simulation results show that:in ZF and MMSE algorithm,interference elimination can improve the SNR of the output signal,and MMSE detection algorithm has better performance.
