(English Abstract)
An UWB communication system are a promising communication technique suitable for the current trends, which are requesting communication methods with the high throughputs and very high speed. A key feature of UWB communication systems is the very narrow pulse used in transmitting the data and PPM(Pulse Position Modulation) for modulating the data. So, the timing accuracy is very important. It is very important to accurately analyze the effect of the timing jitter on the performance of UWB communication systems. In this paper, the methods of analyzing the timing jitter effects on UWB communication systems are introduced. In particular, the channel capacities with timing jitter are calculated including the multiuser access interference.
