Performance analysis of a multipul modulation scheme for UWB communication system

This paper makes a key research of a combined modulation scheme (TH OPPM-BPSM) for UWB systems. The proposed scheme achieves higher data rate by introducing more number of orthogonal pulses in the same pulse repetition interval. It also reduces the system complexity by half by introducing antipodal version of orthogonal pulses. The proposed transmission scheme is analyzed through computer simulations under additive white Gaussian noise (AWGN) channel without multipath and with mutipath respectively.
