Performance evaluations of an asynchronous DS-BPSK UWB system in standard UWB channels by means of characteristic function (CF) method, standard Gaussian approximation (SGA) and simplified improved Gaussian approximation (SIGA) are presented. The standard UWB channel (proposed by IEEE 802.15.3a task group) is employed in the analysis to reflect the actual channel conditions. Firstly, a bit error rate (BER) expression obtained via CF method is presented and the availability of it is analyzed. Then, several key parameters that affect the BER performance are obtained by means of SGA. On the basis of SGA, the validity of IGA method is established in our systems and the accuracy of the BER 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.
