ABER performance of TH-PPM and TH-BPSK UWB multiple access systems using ‘Better Than’ Nyquist pulse

Using dasiabetter thanpsila Nyquist pulse the average bit error rate performance of a time-hopping pulse position modulation and TH-binary phase shift keying ultra-wideband systems has been evaluated in the presence of multiple access interference and additive white Gaussian noise for different system and pulse parameters such as repetition code length, roll-off factor and the symbol repetition rate. Monte Carlo simulation of the UWB systems has been performed to verify the obtained results.
