摘要
针对混沌脉冲位置调制(CPPM,Chaotic Pulse Position Modulation)中系统容易出现的混沌发散现象,提出一种混沌控制方案。通过此控制,解决了原CPPM中可能出现的因发散而导致收发机停止工作这一问题。仿真结果表明该方案简单、有效、可行。
The Chaotic Pulse Position Modulation (CPPM) is a proposed modulation scheme which combines UWB (Ultra-Wide Band) impulse radio with chaotic system. However, the CPPM may cause the system to lose characteristics of chaos between the chaotic pulses. The scheme proposed in this paper provides a control approach without changing the way of modulation. Simulation results show that the proposed scheme is simple and effective.
