Single and Multiple Narrow-band Interferences Suppression in DS-UWB Systems

초록

In this paper, we first develop a new approach to suppress single and multiple narrow-band interferences (NBI) in DS-UWB systems. Based on modeling the NBI with little bandwidth and large bandwidth as a single tone signal and a sinc wave respectively, singular value decomposition (SVD) can be used to estimate these interferences which are then subtracted from the received signal. Simulation results reveal that this algorithm can mitigate the effect of single and multiple NBIs effectively.
