Abstract :
Differential pulse position amplitude modulation (DPPAM) is considered in an ultra wideband (UWB) communication system. DPPAM combines differential pulse position modulation (DPPM) and pulse amplitude modulation (PAM) to provide good performance with low computational complexity. The DPPAM UWB signal is derived from that of pulse position amplitude modulation (PPAM). The frame error rate (FER) of MN- ary DPPAM systems over additive white Gaussian noise (AWGN) and indoor fading channels is analyzed. The results show that the FER performance with 2N-ary DPPAM is better than that with 2N-ary DPPM and PPM, and MN-ary (M>;2) DPPAM provides a good compromise between FER and complexity.
