一种基于跳频编码技术的声系统值班接收系统设计方法

A sort of design method of watch-receiving system of sound-system based on jumping-frequency coding technology

值班接收系统是水下节点必不可少的组成部分。值班接收系统在水下需长期值守,可靠性、稳定性至关重要,同时要尽可能做到体积小、功耗低。本文介绍了一种值班接收系统,采用了硬件频率分析与软件逻辑判别、译码相结合的跳频编码技术,能较好地兼顾以上技术要求。

The watch-receiving system is a absolutely necessary part in underwater node.The watch-receiving system must be on duty for long time.Reliability and stability is very important.At the same time the system should be a small size,and consumes little power.The paper introduces a sort of watch-receiving system.It adopts a combined technique of hardware frequency analyzing and software logic distinguishing.It contents technique request of system.
