In this paper we propose frequency and time hopping pulse position modulation (FTH-PPM) ultra
wideband (UWB) for multiple access communications. We have derived and investigated the bit
error probability for the multi-user synchronous transmitter case in multipath channels with Additive
White Gaussian Noise (AWGN). Simulation results show that bit error probability performance of
FTH-PPM UWB out performs the time hopping pulse position modulated (TH-PPM) UWB system. It
also show that multiuser capacity of FTH-PPM UWB system is much better than TH-PPM UWB
