BER performance comparisons of pulse design methods on TR-MAS UWB systems

Abstract

In ultra-wideband (UWB) communication systems, the time hopped (TH) transmitted reference scheme with multiple autocorrelation sampling detection (TR-MAS) enables the receiver to obtain and capture the received signals autocorrelation side lobe energy while increasing multi-user capacity. The bit error rate (BER) performance of several pulse design methods that meet the federal communications commission (FCC) requirements on the TR-MAS receiver is compared in this paper. The odd or even pulses based system significantly outperforms the prolate spheroidal (PS) pulses when the same pulse duration (or effective bandwidth) is employed in the TR-MAS system for multiple users. Moreover, the tradeoff between pulse width (i.e. spectral efficiency) and BER of both even and odd pulses is presented.
