Abstract :
Statistical moments of the inter-path interference, the inter-chip interference and the intersymbol interference in a direct-sequence binary phase shift keying ultra-wide bandwidth (UWB) system are analyzed for the IEEE UWB channel models. Exact expressions for the first- and second-order moments are derived. Using these expressions, the effects of the channel model parameters and the duration of the monocycle pulse are examined. For comparison, the first- and second-order moments of the signal component are also obtained. An approximation to the probability density function of the signal component is presented, and its accuracy is verified by calculating the bit error rate of a maximal ratio combining Rake receiver.
