Abstract

Timing synchronization is a crucial issue, especially in the ultra-wideband (UWB) systems, since the information conveying pulses are ultra-short. Frequency-modulated differential chaos shift keying (FM-DCSK) is an outstanding modulation technology that has been proven to have a superior capability of anti-multipath fading over multipath fading channels. In this paper, both theoretical analysis and simulation results are presented with regard to the bit error rate (BER) performance of the FM-DCSK UWB communication systems with timing error. It is shown that the simulation results are in accordance with the theoretical analysis, and the timing error induced by later timing causes much more seriously BER performance degradation than that induced by earlier timing.
