摘 要: 对于传统的经典信道多天线(MIMO)模型,空间信道模型(SCM)并不能满足LTE-Advanced系统对于带宽和载频的需求。文章通过增加传输路径,并引入中径的方式将其扩展为扩展的空间信道模型(SCME),以满足系统更大带宽和更高载频的需求,并仿真分析模型各个信道参数的统计特性。 Since the traditional model SCM can't meet the needs of bandwidth and carrier frequency of LTE-Advanced system, this paper extended it to SCME model by increasing the transmission path and the introduction of the middle path, to meet the greater bandwidth and the higher carrier frequency of system. Then the model is simulated and the sta- tistical characteristics of channel parameters are an- alyzed.
