odeling and Analysis of Digital GPS Code Acquisition Circuit Based on Direct IF Sampling
摘要
Abstract
A digital GPS PN code acquisition circuit based on direct IF sampling is presented. Based on the mathematics model of this circuit, the relations between searching rate, probabilities of false-al arm, probabilities of detection and input carrier-to-noise density ratio(C/N0) a re analyzed. A digital system scheme based on the acquisition circuit is propos e d. According to the result of the analysis the digital acquisition circuit can be adopted for improving acquiring performance and system reliability.关键词
