Improved Discrete Definition of Quadratic Time-Frequency Distributions
(
IEEE
, 2010 , Article)
Computation of a time-frequency distribution (TFD) requires a discrete version of the continuous distribution. This discrete TFD (DTFD) should be free from aliasing and conserve all the important mathematical properties ...
Time-Frequency Distributions Based on Compact Support Kernels: Properties and Performance Evaluation
(
IEEE
, 2012 , Article)
This paper presents two new time-frequency distributions
(TFDs) based on kernels with compact support (KCS)
namely the separable (CB) (SCB) and the polynomial CB (PCB)
TFDs. The implementation of this family of TFDs ...
