摘要
声表面波抽头延迟线(SAWTDL)是一种无源器件,将其应用于扩频系统中,可以大大简化系统,提高系统性能.SAWTDL作为匹配滤波器,其相关性能直接关系到系统性能的优劣.文中讨论了频率偏移对SAWTDL相关特性的影响,以及对扩频系统性能的影响.
SAWTDL is a passive device, and may greatly simplify spread spectrum systems and improve the system performance. With a matched filter, SAWTDL correlate characteristic influences directly the system performance. The influence of frequency offset on SAWTDL correlate characteristics and spread spectrum systems are analysed in this paper.
