# Recursive center-frequency adaptive filters for the enhancement of bandpass signals

@article{Kumar1986RecursiveCA, title={Recursive center-frequency adaptive filters for the enhancement of bandpass signals}, author={R. Kumar and R. Pal}, journal={IEEE Trans. Acoust. Speech Signal Process.}, year={1986}, volume={34}, pages={633-637} }

In some signal enhancement and tracking applications, where a priori information regarding the signal bandwidth and spectral shape is available, it is suggested to use a recursive center-frequency adaptive filter instead of a fully adaptive filter. A new adaptive algorithm, namely, the recursive maximum-mean-squares (RMXMS) algorithm, is developed based on the gradient ascent technique for the implementation of these filters. An adaptation mechanism based on the Gauss-Newton algorithm is also… Expand
