Abstract :
Differential pulse position amplitude modulation (DPPAM) is considered in Ultra Wideband (UWB) communic-ation systems in this paper. DPPAM combines differential pulse position modulation (DPPM) and pulse amplitude modulation (PAM) to provide good system performances and low com-putational complexity. A typical format for a DPPAM signal in UWB systems is derived from that of pulse position amplitude modulation (PPAM). The frame error rate (FER) of MTV-ary DPPAM systems over an additive white Gaussian noise (AWGN) channel and indoor fading channels are analyzed. The results show that the FER performance with 2×Nary DPPAM is better than that with 2×Nary DPPM and PPM, and MN-ary (M>;2) DPPAM provides a compromise between FER and complexity.
