Description: Four different classes of adaptive signal cancelers can be used to eliminate narrow-band      interference from a broadband signal: (1) cascaded second- order notch filters, (2)      high-order in-line notch filters, (3) second-order bandpass noise cancelers, and (4)      high-order bandpass noise cancelers. Of the four, a structure based on second-order      bandpass filters used as signal cancelers is found to perform better than the other      structures. The adaptive algorithm for these filters has been proposed by Kwan and      Martin and modified by Petraglia, Mitra, and Szczupak. The Kwan and Martin      structure can be reduced in hardware complexity without degrading performance using      a new adaptive algorithm that out-performs any of the other known structures or      algorithms. This new structure is particularly suited to the elimination of narrow-band      interference in broadband Bi-Phase Shift-Key (BPSK) signals with and without      background noise....
