Abstract
Several quadratic signal representation methods have been successfully used in signal processing. Four quadratic signal representations, Wigner distribution, ambiguity function, signal correlation function and spectral correlation function are the traditional ones. In this paper, we propose a generalized distribution of the four quadratic time-frequency representations. The proposed distributions can have partial time/frequency-lag and partial time-lag/frequency characteristics of signals.
