Multi Pulse Position Amplitude Modulation for ultra-high speed time-hopping UWB communication systems over AWGN channel

This paper presents a novel Multi Pulse Position Amplitude Modulation (MPPAM) scheme for time-hopping ultra-wideband (TH-UWB) communication system. MPPAM is combined version of the Multi Pulse Position Modulation (MPPM) and the Pulse Amplitude Modulation (PAM) where the information is conveyed in the position and amplitude of multiple pulses. The comparison between PAM and Pulse Position Modulation (PPM) was given in aspect of symbol error probability over additive white Gaussian noise (AWGN) channel. It is shown that with proper selection of the amplitude level numbers, pulses and time slots can be achieved better performances at the cost of the hardware complexity and vice versa.
