Adaptive STFT with Chirp-Modulated Gaussian Window

ICASSP 2018accepted

In this paper, we propose an adaptive STFT (ASTFT) with adaptive chirp-modulated Gaussian window. The window is obtained from rotating Gaussian function in time-frequency plane by fractional Fourier transform (FRFT). It is completely adaptive where the two parameters, FRFT rotation angle and Gaussia…

Commuting operator of offset linear canonical transform and its applications

Soo-Chang Pei, Shih-Gu Huang

ICASSP 2016accepted

Linear canonical transform (LCT) is an attractive and useful tool in optics and signal processing. In previous work, a generalization of the LCT with two extra parameters, called offset LCT (OLCT), has been developed. In this paper, a different definition of OLCT is proposed, which has a more concis…
