摘要
分析了UWB室内多径信道模型下接收机的误比特特性。IEEE802.15.3a推荐的UWB室内信道模型是由到达时间服从泊松分布的簇和多径组成的,接着从理论上计算出基于最大比值合并(MRC)分集策略的Rake接收机在超宽带无线通信系统中的性能,最后用计算机仿真和理论结果进行比较。
The probability of receiver in indoor channel model of ultra-wideband is analyzed in the paper. The UWB channel model proposed by IEEE 802.15.3a is composed of clusters and paths distributed according to two poisson models. Then performance of Rake receiver based on MRC diversity tactic is worked out in theory. Finally, theoretical result is verified by computer simulation,
