为了保证信息在不同网络中的安全通信，本文提出了一种基于非相干调制的安全通信方案。发射端通过调制混沌序列和信息位来产生发射信号，而接收端可以在不产生混沌序列同步复制的情况下恢复信息位。每帧可以传输两个信息位。因此，它可以实现高传输速率。性能分析表明，该通信方案具有良好的抗高斯噪声性能，仿真结果表明，在加性白高斯噪声信道中，该通信方案的误码率优于新提出的通信方案。
To securely communicate information in different networks, this paper introduces a novel secure communication scheme using non-coherent modulation. The transmitter is to generate transmitted signal by modulating the chaotic sequences and information bits, while the receiver can recover the information bits without generating a synchronized duplication of the chaotic sequence. Each frame can transmit two information bits. Thus, it can achieve a high transmission rate. Performance analysis demonstrates that the proposed communication scheme has high performance in resisting Gaussian noise and simulation results shows that it has better bit-error rate performance than a newly developed method in the additive-white-Gaussian-noise channel.
