  • 摘要: 为了满足现代通信的需求,多用户接入技术是近年来混沌通信的一个重要发展趋势。为了进一步改善现有多用户混沌通信方案的误码性能,该文提出一种多用户分段移位差分混沌键控(MultiUser Segment Shift Differential Chaos Shift Keying, MU-SSDCSK)通信方案。该方案根据传输的用户数,将MU-SSDCSK中的参考信号等分成m个信号段,再将这m个信号段进行移位,并配以不同的Walsh码,形成相互正交的信息携带信号。文中推导了该系统在加性高斯白噪声信道中的理论误码率公式并进行了仿真。仿真结果表明,该文提出的MU-SSDCSK方案能有效改善系统误码性能,在混沌通信领域具有一定的应用前景。
