Abstract
In this paper, performance of two kinds of ultra wide band systems, namely Direct Sequence (DS) and Time Hopping (TH) over IEEE.802.15.3a channel model is compared by simulation. Simulation results show that DS-UWB performance is better than TH-UWB in multi-user environment. Also, it is indicated that performance in TH-UWB becomes worse with increasing the number of frames. Moreover, simulation is done for several number of fingers by S-Rake and P-Rake for Direct Sequence and Time hopping. Also, performance of Ultra Wide Band (UWB) system over IEEE 802.15.3a channel model is simulated, and their results are compared to upper bound of Bit Error Rate (BER) for UWB in log-normal fading channel.
