摘　　要：根据混沌逆映射的二值性 ,提出了一种基于逆映射的混沌数字通信系统及其实现方案。以Logistic映射为例 ,首次从理论上分析了其在噪声信道下的误码性能。理论分析和仿真结果表明 :逆映射序列具有良好的相关性能 。A chaotic digital communication system based on binary value of chaotic inverse map is presented in this paper. The error performance in noisy channel is analyzed theoretically for the first time using Logistic map. The analysis and simulation results indicated that the inverse map sequence has good correlation performance, the simulation results of error performance are consistent with the theory value.

关 键 词：混沌通信 逆映射 LOGISTIC映射 数字通信系统
