Interference from IEEE 802.11a systems affects ultra-wideband (UWB) systems significantly. In this letter we suggest a novel narrow-band interference (NBI) suppression technique based on the singular value decomposition (SVD) algorithm in time-hopping pulse amplitude modulation (TH-PAM) UWB systems. The SVD algorithm is used to approximate the interference which then is subtracted from the received signals. In contrast to the conventional notch filter and rake receiver our method is more effective and the receiver complexity can be greatly reduced.
