摘要
针对无码间干扰的TH-PPM-UWB通信系统,分析了该系统在IEEE UWB室内多径信道模型下采用Rake接收机时的系统性能,仿真了不同结构Rake接收机的误码率,结果表明,总体上SRake的性能要优于PRake,且两种接收机的性能随着叉指数目的增加都有明显的改善。
This paper analyzes the system performance of TH -PPM -UWB communication system without ISI theoretically when the system uses Rake receiver under IEEE UWB indoor multipath channel model. The simulation of code - error rate for different Rake receiver structure is carried out. The result shows that the performance of PRake is better than SRake＇ s, and the performance of both receivers is improved obviously with the increasing of interdigitated number.
