一种频谱结构可控的复合序列扩频通信方式

针对舰船移动通信中窄带干扰与部分频带干扰等问题，提出一种复合序列扩频通信方式。此方式与直接序列扩频方式相比，具有信号频谱结构可控，能够在整个扩频带宽内形成部分零点而克服干扰影响的特性，与跳频通信方式相比，则具有通过改变复合序列的参数就可控制扩频信号的频谱结构而不需要快速频率合成器的特点。文中介绍了复合序列扩频通信方式的原理，并对其频谱特性，抗干扰效果和多址能力作出分析，模拟与讨论，表明该方式在抗干

A Spread Spectrum Communication Mode of Spectrum Structure Controlled by a Composite Sequence

This paper brings up a spread spectrum communication mode of a composite sequence to solve the problems of interference in narrow bands and some bands of spectrum when vessels are moving. Compared with the spread spectrum mode of direct sequence ,this mode possesses such features as the spectrum structure control of signals and the ability to suppress the interference by forming some zero points in the whole width of the spread band.
