Volterra series representation of time-frequency distributions
Sang-Won Nam, Edward J. Powers · IEEE Transactions on Signal Processing · 2003
This paper addresses a Volterra series representation of bilinear (or quadratic) time-frequency distributions that belong to Cohen's class, whereby the analogy of the bilinear class with a second-order double Volterra series is utilized. In addition, a different viewpoint for the bilinear kernel and a complementary interpretation concerning the quadratic time-frequency distributions are provided.
