1、跳频扩频技术的实现王杰吕【摘要】：现代社会，随着一系列爲新科技的飞速发展，军事领域和民用通信领域对信号的准确性和抗干扰性要求越来越高，山此产牛了具有高度优越性的跳频系统，并且其应用也越來越广泛。本文简述了扩频通信系统的原理、分类、技术指标及应用，重点阐述了跳频系统的组成及工作原理、跳频系统的关键技术包括频率合成技术和跳频同步技术；分层次地介绍了跳频序列的研究方向及现状，这其中乂以蓝牙跳频序列和基于混沌序列的跳频序列族为重点。简要阐述了跳频系统与直接序列扩频系统、跳时系统和DS/FH混A跳频系统的性能比较，从而更加突出了跳频系统的优越性。最后，乂介绍了儿种典型的跳频组网方式，
2、如同步正交组网、同步非正交纽网、异步非正交纽网，针对儿种组网方式分别罗列了其优点，同时也介绍了跳频系统在CDPD、短波数据通信和GSM中的应用。跳频系统虽然也存在一些不足Z处，但它的抗干扰性、低截获性、良好的抗多路径干扰性和女全性等，使其在军事和民丿IJ领域都存在着极其广阔的发展前景。关键词：扩频通信跳频系统跳频同步技术跳频序列族跳频组网技术Frequency-hoppingspreadspectrumtechnologyWangJiechangAbstract：Modernsociety,withaseriesoftherapiddevelopmentofhightech
