【摘要】 本文研究了直扩超宽带通信系统的关键技术----定时抖动及其抑制方法,主要分析了定时抖动产生的原因、分布规律和各种有效的抑制方法。文中第一次对DS-UWB系统定时抖动产生的各种原因进行了分析,给出了的定时抖动的分布规律以及各种可采用的定时抖动抑制方法,特别针对通过信道噪声和干扰来抑制定时抖动的各种有效方法,进行了详细的分析和讨论。更多还原

【Abstract】 The paper investigates the key technology of civil DS-UWB communication systems, i.e., timing-jitter. Through analyzing the reason of timing-jitter and the effect on the DS-UWB systems, we have discussed some effective timing-jitter cancellation meth-ods, mainly including design of anti-timing-jitter pulse shapes, channel interference and noise restraint schemes and adaptive syn-chronization methods.更多还原
