摘　　要：文章简述了扩频数字通信系统相关内容。在扩频技术基础上,引入了跳频扩频系统的模型,并对系统进行了较详细地分析。特别是对扩频跳频系统的特性和实现原理进行较全面地分析,得到了扩频跳频信号的关系数学表达式。同时,通过对跳频扩频的同步过程进行了分析,验证了跳频扩频通信有极强的抗干扰能力和多址通信能力。Article have summarized to expand frequency word communication system related content.On expanding frequently technical foundation have led into to jump frequency expand the model of frequency system, and as system has gone on, analyses comparatively in detail.Especially jumping for expanding frequency realization and the property of frequency system principle is g^ing to analyse comparatively all-sidedly, have gotten to expand frequency jump the relation of frequency signal mathematics expression.Analyse at the same time, through the synchronous course of expanding frequency frequently for jumping, have verified to jump frequency expand frequency communication have the very strong ability of interference rejection with much Zhi communication ability
