直接序列扩频系统的多次驻留顺序捕获

Muitiple Dwell Serial Acquisition for Direct Sequence Spread Spectrum Systems

本文利用矩阵变换方法对多次驻留顺序捕获的平均捕获时间表示式进行了推导,其过程较信号流图法简单。同时还给出了一次、二次及三次驻留顺序捕获系统的平均捕获时间的计算实例。

This paper provides a derivation of an expression for the mean acquisition time of a multiple dwell serial acquisition. Matrix transformation technique is used in derivation procedure, which is simpler than signal flow graph technique. In addition, a practical example of the calculation of the mean acquisition time is included for single, double, and triple dwell serial acquisition synchronization systems.
