摘要

随着混沌移键控技术的发展，调频差分移键控(FM-DCSK)以其优异的性能逐渐成为各国学者关注的焦点。但是，在一个传输周期内，FM-DCSK只有一半的时间发送信号，传输效率很低。本文提出了一种基于沃尔什码的新型FM-DCSK通信系统。研究表明，新通信系统的效率是传统FM-DCSK通信系统的4倍。与传统的FM-DCSK通信系统相比，误码率有了显著提高。该系统在实际通信系统中具有一定的应用价值。

Noise performance of a new FM-DCSK communication system

With the development of Chaos Shift Keying, Frequency - Modulated Differential Shift keying(FM-DCSK) has gradually become the focus of scholars from various countries for its excellent performance. But, within a transmission cycle, FM-DCSK only half the time to send signals, the transmission efficiency is very low. In this paper, we present a new kind FM-DCSK communication system which based on the Walsh code. The studies have shown that, the efficiency of the new communication system is 4 times as the traditional FM-DCSK communication system. The bit error rate has a significant improvement compared to the traditional FM-DCSK communication system. The new system has value for application in the actual communication system.
