| 摘 要： | 在差分混沌键控和混沌相位调制的基础上,提出一种新的混沌通信系统,并给出了调制解调框图.除了具有混沌调制系统原有的宽带特性之外,最主要的特点是使单位码元符号包含的信息比特提高为1+log2M,从而能提供更快的传输速率.并在高斯信道中进行了计算机数值仿真,结果表明其误码率性能还优于差分混沌键控.

| Abstract: | On the basis of differential chaos shift keying and chaotic phase modulation,a combined communication system is proposed.In addition to the broadband characteristics of original chaotic modulation methods,the main improvement is that the information bits of unit symbol included are increased to 1+log2M.Then the system is simulated in Gauss white noise channel,and the performance of the bit error rate versus the signal-noise-rate is obtained,which depends on the number of chaotic samples and chaotic phase nu... |
