Abstract :
A coded N-ary pulse position modulated (PPM) ultra-wide bandwidth (UWB) impulse radio which exploits the chaotic time hopping and the polarity randomisation is considered. It is shown that the proposed system has a noise-like spectrum and its multi-user system is discussed. The bit error rate performance is confirmed by simulation based on the UWB indoor channel model.
