PN码捕获技术是DS -CDMA蜂窝移动通信系统的关键技术。这里提出了一种基于能量窗的捕获技术 ,基于能量窗的捕获技术有效地利用了CDMA系统固有的多径分集能力 ,捕获对象是多径信号。研究结果表明对有效多径成分进行捕获有比单径捕获和跟踪更好的性能。
PN code acquisition technology is the key technology of DS-CDMA cellular mobile communication system. In this paper, we propose a capture method based on energy window. The capture technique based on energy window effectively utilizes the multipath diversity capability of CDMA system. The captured object is multipath signal. The results show that the capture of effective multipath components has better performance than single-shot capture and tracking.
