摘　　要：介绍了UWB多径信道的特征,研究基于Intel的UWB多径信道模型。利用Matlab仿真了不同实际环境下UWB的多径信道响应,并在此基础上利用蒙特卡罗方法,分析比较了采用不同调制方式(BPSK、二进制正交和二进制DPSK)时RAKE接收机的误码率性能,发现采用BPSK方式调制时,UWBRAKE接收机的性能最优。In this paper,characteristics of the multi-path channel response of ultra-wideband(UWB)communication system are introduced. The UWB Multipath Channel Model from Intel is theoretically analyzed. Simulations of UWB channel responses under several realistic circumstances are done using Matlab. In addition, based on this mul-tipath channel model and Monte Carlo analytic method, performances of RAKE receiver using different kinds of modulation schemes are studied and simulated in terms of bit error rate. Simulation results are presented. It is found that performance of the RAKE using BPSK modulation is the best.
