Abstract :
The impact of multipath propagation on ultra wide band (UWB) radio, which is carrier free, is quite different from that on conventional radio. This paper presents a theoretical analysis of the bit error rate (BER) performance of binary pulse-position-modulation (PPM) UWB radio in multipath channels. The BER formula is derived. Particular attention is paid to the effect of the propagation time-delay on the BER performance. It is also noted that, for the PPM scheme, the multipath propagation time-delay may lead to unbalanced BERs over "0"-"1" in some particular multipath channels.
