This paper presents an analysis of the performance of the multiband orthogonal frequency division multiplexing (MB-OFDM) system for ultra wideband (UWB) communication in the presence of interference from a single-carrier IEEE 802.16 WiMAX system operating in the 3.5 GHz band. The intent of our analysis is to provide theoretical justification for the commonly-used bandlimited Gaussian noise model for this type of interference. We present an exact analysis of the uncoded bit error rate (BER) of the MB-OFDM system, based on Laplace transform techniques. We also present a simple and relatively accurate Gaussian approximation for the WiMAX interference.
