两级混合型DS/CDMA捕捉结构

A Two-stage Hybrid Acquisition Scheme for DS/CDMA

提出一种基于匹配滤波器的混合型快速捕捉结构 ,将固定停顿时间与可变停顿时间相结合 ,实现可靠快速的捕捉 .数值分析结果表明 ,与传统两级固定停顿时间结构相比 。

This paper presents a two stage hybrid rapid acquisition scheme based on matched filter.The scheme combines the fixed and the variable dwell time mechanisms.It enables the sequential detector to implement reliable and rapid acquisition.It is shown by numerical analysis that the performance of the scheme is greatly improved compared with that of traditional two stage fixed dwell time schemes.
