In this paper, the bit error rate performance of the Rake reception of binary signals over the IEEE 802.15.3a ultra- wide bandwidth channel model is evaluated. Instead of using Gaussian approximation for the PDF of the total disturbance, a more accurate method is introduced by using the characteristic function of the interference and the additive white Gaussian noise. A formula for the evaluation of the bit error rate performance of ultra-wide bandwidth systems is thus derived, which can be rapidly calculated by using Gaussian Hermite quadrature with excellent accuracy.
