摘要
从抗截获的角度出发,提出了一种基于隐蔽信道的直扩小跳频的通信方案。文章首次对直扩小跳频的基本概念进行了描述,并对其原理、具体实现方案及抗截获性能进行了分析。
In order to improve the anti-interception performance of communication system, a new scheme named direct-sequence spread-spectrum combined with narrow-band frequency hopping communication based on secret channel is proposed. The main concept of the new communication scheme is presented in this paper for the first time, followed by the analysis of its basic theory, implementation and anti-interception performance.
