UWB multiple access performance in synchronous and asynchronous networks

Abstract

Relative to asynchronous network performance, a synchronous UWB network with Gold coded TH-PPM modulation yields average BER improvement of −6.30 dB with no multipath present (NMP=0) and −0.30 dB for NMP=10. Synchronous DS-BPSK modulation yields improvement of −13.01 dB (NMP=0) and −2.51 dB (NMP=10). For a single communication link, Pb increases by a factor of 1.5 (TH-PPM) and 25 (DS-BPSK) per multipath replication.
