Performances of hybrid Amplitude Shape Modulation for UWB communications systems over AWGN channel in a single and multi-user environment

This paper analyzes the performance of the hybrid Amplitude Shape Modulation (h-ASM) scheme for the time hopping ultra-wideband (TH-UWB) communication systems in the single and multi-user environment. h-ASM is the combination of Pulse Amplitude Modulation (PAM) and Pulse Shape Modulation (PSM) based on modified Hermite pulses (MHP). This scheme is suitable for high rate data transmission applications because b = log2(MN) bits can be mapped with one waveform. The channel capacity and error probability over AWGN channel are derived and compared with other modulation schemes.
