Abstract It is usually assumed that the perfect propagation delay has been achieved between the receiver and the transmitter, the receiver and the transmitter synchronize per-fectly, actually it is impossible to do this. Because of this, this paper proposes a single user TH-SS PPM UWB system with synchronization timing tracking ability, designs the synchronization timing tracking scheme, derives the receiver demodulator output SNR while the synchronization timing error exists between the transmitter and the receiver. The syn-chronization timing error has great effects on the system BER performance. Theoretical analysis and simulation results indicate that the less the synchronization timing error, the less the system BER.
