Ultra wideband communication systems provide high data rate transmission at low power. The transmission of narrow pulses can be implemented using time hopping or direct sequence techniques. This work deals with the comparison of TH-BPSK and DS-BPSK systems in lognormal fading channel with 802.11a interference. DS-BPSK presents slightly better bit error rate performance than TH-BPSK when line-of-sight multipath channel, and high multi user interference. When high dense NLOS channel is considered both systems shows similar behaviour.
