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 o f differentia l chaos sh ift key ing and chaotic phase m odulation, a comb ined comm un ication system is proposed. In addition to the broadband charac teristics of or ig ina l chao tic m odulation m ethods, the m a in im provement is that the in fo rm ation b its of unit symbo l included are increased to 1+ log2M. Then the system is simu la ted in Gauss w hite no ise channe,l and the perform ance o f the b it error rate ve rsus the signa-l no ise-rate is ob tained, w hich depends on the number o f chao tic samp les and chao tic phase num ber. The results show that the bit erro r rate is even decreased com pared w ith DCSK.
