混沌同步研究的Matlab程序。。对于初学者的有很大帮助(Chaos synchronization of the Matlab program. . Great help for beginners)

由于多径和移动台运动等影响因素，使得移动信道对传输信号在时间、频率和角度上造成了色散，如时间色散、频率色散、角度色散等等，因此多径信道的特性对通信质量有着至关重要的影响，而多径信道的包络统计特性成为我们研究的焦点。根据不同无线环境，接收信号包络一般服从几种典型分布，如瑞利分布、莱斯分布和Nakagami-m分布。(Because multipath and mobile and other sports influence factor, makes mobile channel in transmission in time and frequency signal and Angle caused the dispersion, such as time dispersion, frequency dispersion, Angle dispersion, and so on, thus multipath channel of communication with the characteristics of quality is very important, while the effect of multipath channel (the statistical properties become the focus of our research. According to different wireless environment, receiving signals envelope general subject to several typical distribution, such as Rayleigh distribution, rice distribution and Nakagami-m distribution. )
