Waveform distortion performance evaluation using practical antennas in deterministic multipath impulse radio channels

As a potential future technology, impulse radio is a promising new reliable data transmission method for time-sensitive applications. However, owing to the complex nature of ultra-wideband (UWB) channels used in practice, there are many design problems that remain to be resolved. This study looks into some UWB channels classified as waveform distortion for which the authors present an implementation-oriented analysis to investigate the performance of impulse radio systems using antennas for a special class of deterministic multipath channels. This study analyses the waveform distortion along signal path to identify the effect of non-idealities in the system and evaluates overall performance of system in terms of bit error ratio observing the waveforms received at the correlator. Through simulation results practical aspects of the impulse-radio transceivers are discussed. From some of the results, the authors provide an antenna selection strategy for some propagation environments.
