摘要

为解决高效差分混沌键控（HE-DCSK）系统判决变量中信号内干扰的不利影响问题，提出一种无信号内干扰的高效差分混沌键控通信方案。该方案通过改变混沌载波的构造方式，确保在相同信息时隙内传输的两路携带不同信息的已调混沌信号严格正交，彻底去除了接收机判决变量中的信号内干扰分量。分析和仿真表明，所提的新系统可以大大改善HE-DCSK系统的误码性能。

Abstract

To eliminate the adverse effect brought by the intra-signal interference components in decision variables in high efficiency differential chaos shift keying system

a novel high efficiency differential chaos shift keying modulation scheme without intra-signal interference was proposed.By changing signal format of the chaotic carriers

the proposed scheme makes the two modulated chaotic signals transmitted in same time slot strictly orthogonal

which removes all possible intra-signal interference components from all decision variables clearly.It is shown by the analysis and simulation results that the proposed system has much better performance than HE-DCSK.
