dc.description.abstractUltra Wideband systems impose a stringent requirement on the jitter performance of the system clock, which commonly exhibits colored timing jitter. This thesis firstly investigates the Bit Error Rate (BER) performance of a binary Pulse Position Modulation single-user UWB communication system subjected to colored gaussian timing jitter. Theoretical and simulation analyses show that colored jitter degrades BER performance more than white jitter, with greater degradation as jitter bandwidth decreases. Secondly a new jitter compensation algorithm is proposed to improve BER performance under colored timing jitter. It tracks the jitter by performing correlation between received signal and template and using the last decoded bit. This information is then used with known clock jitter bandwidth and jitter root-mean-square (RMS) value in deciding the current bit according to the maximum likelihood criterion. Simulation results show that it is effective in improving BER performance, with greater effectiveness as jitter bandwidth decreases and jitter RMS value increases.
