| 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07?dB的性能改善.

| Abstract: | The evolving process of channel matrix from traditional joint detection (JD) systems to traditional multiinmultiout (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 (07?dB) bit error rate (BER) performance. |
