This paper proposes a simple method of realization of center-frequency adaptive filters for high-accuracy detection of band-pass signals immersed in a broadband signal. Our method extends the conventional method proposed by Kumar and Pal. While the conventional center-frequency adaptive filters were mathematically difficult to describe in the case of high filter order, our method provides a simple procedure to construct any kind of high-order center-frequency adaptive filter. We achieve this… Expand
