广义MIMO通用信道矩阵建模
Modeling of the Generalized MIMO Channel Matrix
【摘要】 推导了传统单天线联合检测(JD)系统传输矩阵到传统多输入多输出(MIMO)系统传输矩阵的演化;提出了广义MIMO通用信道矩阵模型.推导表明,MIMO与联合检测可以在该模型中得到统一;基于该模型,传统MIMO系统的贝尔实验室分层空时码(BLAST)检测算法应用于联合检测系统,可得到约0.7 dB的性能改善.
【Abstract】 The evolving process of channel matrix from traditional joint detection(JD) systems to traditional multi-in-multi-out(MIMO) systems was presented and a novel generalized MIMO channel matrix model was proposed.The evolving process shows that,MIMO and JD can be unified in this model.Moreover,with such a channel matrix model,the detection algorithm of Bell lab layered space time(BLAST) code in traditional MIMO systems can also be used in JD systems with a better(0.7?dB) bit error rate(BER) performance.
