| Abstract: | 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 |
