ABSTRACT

This paper discusses the impact of tuning the temporal width of an information carrying waveform on the bit error rate performance of an impulse radio ultrawide band (IR-UWB) communication system. Theoretical expressions are developed for the energy per bit in terms of the pulse width of its encoding waveform. Two of the most widely adopted types of IR-UWB signaling waveforms are considered. It is shown that, under spectral constraints, only a discrete set of pulse widths should be possessed by the IR-UWB signaling waveforms such that the minimum bit error rate performance is achieved. The accuracy of the analytically obtained expressions is confirmed by the excellent agreement with the results obtained via numerical simulations.
