直扩信号加扰浅析

Brief analysis of the disturbing to DS-signaling

直扩信号由于具有优良的特性而被广泛应用于现代通信领域。随着现代信号处理技术的进步和信号盲检测理论的发展,直扩信号因其固有的周期性和循环平稳性而使其为各界所看好的抗截获破译能力逐渐消逝;为了保持其昔日的辉煌,增强其抗截获破译能力,提出通过对直扩信号进行加扰来改变其统计特性加强其抗截获能力的思想方法,并对加扰后直扩信号的特性进行了探讨分析。

DS-signaling is widely used in the field of modern communication. Along with the advancement of modern signal processing technique and the development of modern signal blind detection, the resisting intercepting and decrypting competence of DS-signaling is fading away because of its inherent periodicity and cyclostationary characteristic. In order to keep the brilliance of former days and enhance its competence of resisting intercepting and decrypting, the article puts forward the thought that changes the statistics characteristic of DS-signaling by disturbing. And probes into the performance of the disturbed DS-signaling.
