【摘要】 将滤波算法和自适应解调算法相结合,比较研究了混沌调制通信系统的几种解调技术.仿真结果表明,将自适应滤波算法和自适应解调原理相结合的方法能够较好抑制信道噪声,并能有效地提取混沌系统的系统参数和恢复消息信号.
【Abstract】 Chaos-based wideband communication is an interesting topic,in which chaotic modulation and demodulation is an important realizing technique.Combining adaptive filtering algorithm with adaptive demodulation algorithm,several demodulation techniques of chaotic modulation communication systems are studied comparatively.The results by computer simulation indicate that the demodulation method by using the combined adaptive filtering and adaptive demodulation algorithms can effectively reduce channel’s noise and recover message signals.
