Ultra wide-band (UWB) technology is suitable for high data rate short range wireless communication, localization, and imaging techniques. In many applications, UWB devices may be operating in environments with impulse noise sources or narrow band interferers, called as impulse interferer. Impulse noise of high amplitude and random occurrences can overlap a UWB signal making UWB signal recovery difficult at the receiver end. The conventional UWB receiver is not optimal for impulse noise since they are designed for additive Gaussian noise assumption. In this paper, we propose a robust UWB receiver designed to mitigate the detrimental effects of impulse noise by exploiting the distinct characteristics of the signal and impulse noise. The bit error rate (BER) performance of binary phase shift modulated UWB pulses is demonstrated in the presence of impulse noise using the proposed receiver design. Simulation results establish robustness of the proposed method to the presence of additive impulse noise.
