Abstract

We introduce a new method for the time-scale analysis of non-stationary signals. Our work leverages the success of the 'time-frequency distribution series / cross-term deleted representations' into the time-scale domain to match wide-band signals that are not well modeled in terms of time and frequency shifts. Using a wavelet decomposition and the Bertrand time-scale distribution, we locally balance linearity and bilinearity in order to provide good resolution while suppressing troublesome interference components. The theory of frames provides a unifying perspective and leads us to insights into the cross-term deleted representations.
