Abstract :
Differential pulse position modulation (DPPM) is considered in Ultra Wideband (UWB) communication systems in this paper. A typical format for a DPPM signal in a UWB system is derived from that of a PPM signal. The error probabilities of DPPM with receive diversity over additive white Gaussian noise (AWGN) channels and Nakagami fading channels are analyzed. Performance results are presented which show that the frame error rate (FER) with DPPM is better than that with PPM, and the FER performance can be improved by receive diversity.
