Abstract

The bi-phase modulation (BPM) for ultra-wide bandwidth (UWB) systems has some advantages over other modulation schemes such as a smoother power spectral density and higher resistance to jitter. In this paper, we estimated the BER performance of the BPM for two different data rates, 10 Mbps and 100 Mbps, in a multipath environment through simulation and compared the results with that for the pulse position modulation (PPM). Our results indicate that the BPM performs better than the PPM for both data rates. The BER performance is sensitive to the data rate for both modulation schemes, and the performance gap between the two data rates increases as the SNR increases.
