| 摘 要： | 在最终被IEEE802.15.SG3a研究组采纳的Intel信道模型的基础上,针对DS-PAM-UWB系统研究分析了不同Rake接收方案对系统性能的影响.对Arake、Srake、Prake等3种不同接收机结构、不同支路数,以及不同合并方案下的Rake接收机性能进行了仿真分析,并比较了DS-PAM和TH-PPM两种不同调制方式下的Rake性能,仿真结果表明DS-PAM-UWB的系统性能在Intel信道环境下优于TH-PPM-UWB系统性能约3 dB.

| Abstract: | Based on the Intel channel model approved by IEEE802.15.SG3a group,the influence of different Rake receivers upon DS-PAM-UWB system performance is analyzed in this paper.Simulation and analysis are developed in the area of BER performances of Arake,Srake,Prake using different number of Rake taps.Besides,two types of diversity schemes are considered,maximal ratio diversity combination and equal gain diversity combination.System performance using different methods of modulation,DS-PAM and TH-PPM,is also compared.The simulation result shows that performance of DS-PAM-UWB is 3 dB better than that of TH-PPM-UWB. |
