| 摘 要： | 超宽带信号经多径信道传播会产生严重的时间弥散。采用RAKE接收是提高超宽带接收机性能的重要手段。介绍了Intel的UWB多径信道模型。对采用TH-PPM调制的超宽带系统在Intel多径信道模型下A-RAKE，S-RAKE和P-RAKE的误码率性能和对系统复杂性的要求进行了分析。在实际的RAKE接收机设计中，S-RAKE和P-RAKE的性能与支路数有关，S-RAKE要优于P-RAKE。S-RAKE和P-RAKE的性能随着支路的增加而减小。

| Abstract: | In multipath environments,ultra-wide band signals suffer from severe time dispretion.RAKE reception is an important way to boost the performance of ultra-wide band receivers.In this paper,characteristics of the multipath channel response of ultra-wide band(UWB) communication system are introduced.With the assumption that TH-PPM modulation is used,the BER performance and system complexity of RAKE reception in Intel channel model are analyzed.The performance of S-RAKE is better than that of P-RAKE,they both are related to the fingers of RAKE receiver.The difference of performance of S-RAKE and P-RAKE is reduced with the increasing of fingers. |
