Abstract

A bit error rate (BER) analysis of an asynchronous DS-BPSK UWB system in dense multipath channels by means of standard Gaussian approximation (SGA) and simplified improved Gaussian approximation (SIGA) is presented. The standard UWB channel (proposed by IEEE 802.15.3a task group) is employed in the analysis to reflect the actual channel conditions. Several key parameters that affect the BER performance are obtained by means of SGA. On the basis of SGA, the validity of improved Gaussian approximation (IGA) method is established in our systems and the accuracy of the bit error rate expression obtained via SIGA is demonstrated with Monte-Carlo simulations. Besides, the impacts of several different kinds of transmitted pulses on BER performance are investigated with numerical examples.
