In this work, we attempt a pulse shaping method, considering the channel as a raised-cosine filter and futher optimized using genetic algorithm (GA). The pulses designed are not only meet the constraints of FCC for UWB, but also spectrally efficient. Pulses generated have a very short duration to reduce multipath interference and are mutually orthogonal. Average bit error rate (ABER) performance of time-hopping binary phase shift keying (TH-BPSK) UWB systems has been evaluated in presence of multiple access interference (MAI) and additive white Gaussian noise (AWGN) for variety of different scenarios, such as, number of users, number of slots per frame and modulation types.
