UWB Receiver Based on a Filter Bank Architecture for Suppression of Narrowband Interference Noise

Ultra wideband (UWB) links are inherently subject to narrowband interference from other communication links which will result in frequent disruptive outage conditions. This paper proposes a solution for suppressing the narrowband interference noise based on analog filter bank preprocessing in conjunction with maximum ratio combining (MRC) and generalized matched filter (GMF) processing. This receiver architecture requires significantly less processing than the optimum GMF processing while providing excellent suppression of the narrowband interference that rivals the comparative performance of the GMF.
