High performance signal-modeling by pencil-of-functions method: Band-pass case
V.K. Jain, Tapan K. Sarkar · IEEE Transactions on Acoustics Speech and Signal Processing · 1986
We discuss an extension of the pencil-of-functions method, namely, the use of band-pass processing filters, and show that this leads to considerably enhanced modeling of band-pass signals. The theory of such processing is presented and an example is given which demonstrates the efficacy of the technique at moderate to high levels of data noise.
