摘要：

Coexisting with many concurrent narrow band services, the performance of UWB systems will be affected considerably by them due to the high power of these narrow-band signals with respect to the UWB signals. Specifically, IEEE 802.11a systems which operate around 5 GHz and overlap the band of UWB signals will interfere with UWB systems significantly. In this paper, a novel narrow-band interferences (NBI) suppression technique based on singular value decomposition (SVD) algorithm for two UWB systems is presented. The two systems are direct sequence ultra-wideband (DS-UWB) system and timing hopping (TH) binary pulse amplitude modulation (PAM) UWB system. SVD is used to approximate the interferences which then are subtracted from the received signals. The proposed technique is simple and robust. Simulation results show that the proposed new technique is very, effective.
