摘要
该文提出了一种新的带序贯滤波的全数字PN码跟踪环,并通过建立环路跟踪过程的等效数学模型,分析了瑞利信道下环路的非线性跟踪性能,并对理论数值结果和仿真结果进行了比较分析。结果表明,该跟踪环在衰落信道下能获得满意的跟踪性能。
A new digital PN code tracking loop with a sequential filter is dynamic process is provided to derive the loop＇s nonlinear performance proposed, and an equivalent model of the loop＇s The performance is also analyzed by computer simulation under Rayleigh fading channel. The results show that this loop has satisfactory performance under fading environments.
