Research on Spread Spectrum Communication Based on Digital Chaotic Encoder

结合数字混沌序列的混沌特性,设计了一种基于数字混沌编码器的键控混沌扩频通信方案。该方案的收发两端采用相同结构的数字混沌编码器,产生完全同步的数字混沌序列,从而实现接收端的相关解扩。仿真结果表明,该方案具有良好的抗噪声性能和较高的安全保密性,能满足数字通信的误码率性能要求。

According to the quasi-chaotic feature of digital chaotic sequence,which is structure-simple and implement-easy,a spread spectrum communication scheme based on digital chaotic encoder is proposed in this paper.In order to achieve the relevant dispreading of the transmitting and receiving terminal,the same digital chaotic encoder is utilized to generate synchronous chaotic sequence.Simulation results show that the program possesses an excellent anti-noise performance and high security and confidentiality.
