Abstract
This paper describes interpolated discrete Fourier transform (IpDFT) for parameter estimation of sinusoidal and damped sinusoidal signals analyzed with a sin(alpha)(x) window. For alpha = 0, 2, 4, . . . sin(alpha)(x) windows are Rife-Vincent class I (RVI) windows, for which IpDFT algorithms are known. We present a new IpDFTs for a = 1, 3, 5,.... The bias-variance trade-off of the proposed IpDFT fits between results offered by RVI windows, e. g., for alpha = 1, we get higher noise immunity than Hann (RVI order 1, alpha = 2) window and lower bias than rectangular (RVI order 0, alpha = 0) window.
