本文提出一种新的延迟锁定环路的大步进快速捕获方法
主要解决目前尚未很好解决的低信噪比长序列伪随机码的快速捕获问题。文中讨论了大步进快速捕获延迟锁定环路的原理与实现
分析了这种环路的平均捕获时间、解扩相关器的输出成分及大步进搜索时的虚警与检测概率。
In this paper a new method of large step fast acquisition of delay locked loop(DLL) is proposed.The purpose is to solve the fast acquisition problem of the low S/N long period PN code that has not yet been solved.The principle and realization of the large step fast acquisition DLL are discussed.The average acquisition time of the loop
the output ingredients of the despread correlator
and the false alarm probability and probability of detection under the condition of large step fast acquisition are analysed.
