| 摘 要： | 在相同冗余度下对比研究调制技术和编码技术的性能指标,以图改善超宽带发射参考(TR)接收机的工作效果。从理论上推导基于调制的平均TR接收机和基于BCH编码的TR接收机的误码率表达式,并对其在多径信道下的检测性能进行Matlab仿真和比较。结果表明:BCH编码在近距离高信噪比时降低TR接收机的误码率效果更好;平均TR调制在远距离低信噪比时更有优势,但随参考信号个数增加性能增益将变得十分有限。

| Abstract: | In order to improve the performance of Ultra-wideband(UWB) transmitted-reference(TR) receivers,two approaches are presented,of which,one is averaged TR receiver based on modulation and another is BCH coded TR receiver based on encoding.Moreover,a comparative study is given to find out which one can provide much better performance improvement with the same amount of signal redundancy.The expressions of bit error rate(BER) for the two receivers are deduced respectively and their detection performance in a mul... |
