Abstract :
Pulse-position modulation (PPM) is one of the popular modulations for ultra-wideband (UWB) communications. The modulation index, δ, used in a time-hopping PPM scheme plays an important role in the reduction of bit error rate introduced by noise. In this paper, we mathematically show the pulse-width dependent, Tp, optimal modulation index that yields the least probability of error based on a given SNR for PPM with different orders of Gaussian monocycle shaping function.
