N2 - Power control techniques are adopted in narrow-band systems to overcome near-far effects by varying transmitted power levels so that all signals are received with equal power level. However, since the transmission data rate is too high in Ultra-Wideband (UWB) in which multimedia communication is desired to realize, it is impossible to accomplish perfect power control with current technologies and hardware, and therefore performance of UWB systems will be reduced. A model of UWB system under imperfect power control is proposed, and system performance with this model is analyzed. Since system performances are different by utilizing different waveforms, to improve the performance, an optimal waveform is adopted in UWB system, and the improvement of system performance is shown by comparing to the performance using Gaussian waveform.
