Abstract :
Ultra-wideband (UWB) has become one of the key technologies in wireless communication industries. In this paper we discuss and evaluate the performance of UWB under different channel conditions when it is applied for wireless sensors. The simulation was carried out for various detection and modulation schemes. Simulation results confirm that UWB with coherent detection outperforms the noncoherent detection the difference being 10dB in SNR to achieve the same performance. Coded UWB improves the performance by another 2dB. Low rate UWB performs better than the high rate one.
