Performance Comparison of Ultra Wideband Impulse Radio

This paper introduces time-hopping pulse-position-modulation, binary time-hopping pulse-amplitude-modulation and direct sequence ultra wideband first. Then we analyze the bit error rate performances of the three Ultra Wideband radio models in additive white Gaussian noise and in the presence of single-tone jamming and the results obtained are compared by theoretic analysis and computer simulation. The simulation results show that the Ultra Wideband radio is of good performance in low SNR indeed, and the bit error rate performances of binary time-hopping pulse-amplitude-modulation and direct sequence ultra wideband schemes are better than that of time-hopping pulse-position-modulation scheme.
