Abstract

Ultra wideband (UWB) is a promising technique for wireless communications. It is a carrier-free (base-band) technique, which can greatly reduce the complexity and cost of the transceiver. In contrast with conventional communication systems using the "sine wave", UWB information is carried in a very short pulse, which covers an extremely wide spectrum bandwidth. Several candidate monocycle (narrow pulse) shapes are investigated, their spectrum characteristics and BER performance in AWGN using pulse position modulation (PPM) are simulated, and the results are compared. Their performances in the fading multipath channel are also investigated.
