基于SM调制的Massive MIMO信号检测算法

摘要

In recent years,large-scale multiple-input multiple-output (Multi-Input Multi-Output, MIMO)signal detection problem has attracted much attention,this paper studies the belief propagation (Belief Propagation,BP)-based algorithm on the proposed (Message Passing Detection for Spatial Modulation,MPD-SM) detection algorithm based Massive MIMO information transfer process. A new spatial modulation under the simulation comparison chart under two different modulation patterns,the results show that,under different circumstances modulation order,the performance of the proposed algorithm is superior to the traditional detection algorithm under the M-MIMO. And to some extent,the complexity of large-scale multi-user MIMO detection is reduced and the detection efficiency is improved.%近几年来，大规模多输入多输出（Multi-Input Multi-Output，MIMO）的信号检测问题已经引起了人们的关注，在研究了置信度传播（Belief Propagation，BP）算法的基础上，提出了一种新的空间调制下的基于信息传递过程的Massive MIMO（Message Passing Detection for Spatial Modulation，MPD-SM）检测算法，给出了两种不同用户天线数下的仿真对比图，结果表明，在这两种仿真下，所提算法性能要优于M-MIMO下传统的检测算法，且在一定程度上降低了大规模MIMO多用户检测的复杂度，提高了检测效率。
