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.
