Waveform Distortion and Performance of Impulse Radio with Realistic Antennas in Deterministic Multipath Channels

The waveform distortion and performance of an ultra-wideband (UWB) impulse radio system are investigated considering both realistic antennas and deterministic multipath channels. The effects of non-idealities in the real systems are evaluated by analyzing the waveform distortion along the signal path, performance of the overall system in terms of bit-error rate (BER) is obtained by observing the eventually received waveforms before the correlator. The simulated waveform distortion and performance degradation resulting from realistic antennas and multipath channels are discussed. This work demonstrates the implementation oriented analysis of pulse-based UWB systems, as part of the result, the selection of antenna over different propagation environment is given.
