Abstract
In this paper, we study the capacity of non-orthogonal pulse position modulation (NPPM) for ultra-wideband (UWB) communication systems. The channel capacity of NPPM is determined for a time-hopping multiple access UWB system. It is shown that with proper selection of the pulse waveform and modulation index, NPPM can achieve a higher capacity than orthogonal PPM.
