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.
