频率跳变系统码跟踪电路研究

Study of Code Trace Circuit for Frequency Skipping System

对无线数据传输设备中使用的频率跳变扩频系统的码跟踪电路作了研究,首先提出了宽带信号的最佳跟踪问题,然后给出了频率跳变扩频系统的全时间前、后非相干码跟踪电路。分析了码跟踪电路的输入和输出关系及延迟锁定鉴别器输出端功率密度、鉴别特性曲线、码跟踪抖动等主要性能参数。

This paper studies code trace circuit of the frequence skipping system in the wireless data transmission equipment. A broad band signal optimum trace question is proposed and a total time former and later uninterrupt code traoe circuit of fre-quency skipping and frequency extending system are given. The input and output relation of code trace circuit, primary performance parameters of the output power density, discriminative characteristic diagram, code trace shake of the deky locked discriminator are amalyzed.
