摘要: 该文基于混沌脉冲位置调制(CPPM)提出了一种新型可用于超宽带冲击无线电(UWB-IR)的通信方案混沌脉冲开关键控。该方案克服了混沌脉冲位置调制方法存在的问题，具有保密性好、可靠性高、设备的实现更加简单等优点。分析和仿真表明，在非理想定时情况下，该文提出的新系统具有比CPPM更好的解码性能。Abstract: Based on the Chaotic Pulse Position Modulation (CPPM) method, a novel communication scheme is proposed for Ultra-Wide Bandwidth Impulse radio Communication System (UWB-ICS) in this paper. The proposed scheme can overcome the disadvantages existing in CPPM, having the desired features of communication privacy, reliability and lower design complexity. It is shown by the analysis and simulation results that Chaotic Pulse On-Off-Keying (CPOOK) has better performance than CPPM in the case of non-ideal timing.
