摘要 基于恒虚警概率算法提出了一种自适应双驻留直接序列扩频的伪随机码(PN)捕获方法,给出了其原理框图,分析了其在加性高斯白噪声信道和瑞利衰落信道下的捕获性能。理论分析和计算机仿真结果表明:此方法性能优于传统的固定门限双驻留捕获方法,适合移动通信环境的变化。 Based on CFAR, an adaptive double-dwell acquisition method for DSSS system and its principle block diagram are introduced. The results of theoretical analysis and the computer simulation for the performance of the acquisition system both in AWGN channel and Raleigh channel indicate that the adaptive double-dwell acquisition method has a better performance than the conventional fixed threshold double-dwell acquisition one, and it proves its an effective method in various mobile communication environments.
