摘要 通过对LTE系统下的MIMO信号自适应检测进行研究,分别在高相关与适度相关信道模型下结合有、无HARQ两种状态,给出了4种不同情况下LMMSE、SIC 2 it、8-best和SSFE算法性能仿真,并对仿真结果进行了详尽分析比较,在此基础上给出了基于系统吞吐量的MIMO信号自适应检测的算法性能评价标准,并对各算法间状态转换给出了建议。 This paper has studied the adaptive detection of MIMO signal under the LTE system.Specifically the paper has listed performance simulations of four algorithms like LMMSE、SIC 2 it、8-best and SSFE under four different cases resulted from two channel models of high correlation and moderate correlation combining with or without HARQ. And the simulation results have been analyzed and compared in detail,on the basis of which we have discovered the evaluation criteria of algorithm performance of the adaptive detection of MIMO signal based on the system throughput and made suggestions on state transitions among different algorithms.
