UWB links are inherently subject to narrowband interference from other narrowband communication links. This paper proposes a solution for suppressing these narrowband interference sources which is based on using an analog filter bank (AFB) for pre-processing the received signal. The AFB outputs are subsequently processed by a combination of maximum ratio combining (MRC) and generalized matched filter (GMF) processing. This receiver architecture requires significantly less processing than the optimum GMF processing while rivaling its performance in the context of narrow band interference (NBI). Furthermore as the AFB consists of low Q low order bandpass filters, monolithic integration is practical resulting in a low cost manufacturable solution to the UWB receiver. Analysis and simulated performance of the AFB architecture are presented in this paper. As well the theoretical capacity and bit error rate as a function of the AFB parameters are presented. These results are presented as a function of the overall receiver complexity for different compositions of wide band and narrow band channel noise.
