Abstract :
This paper introduces two new methods for discrimination of non-stationary sinusoids within a single analysis frame. Both methods use data from frequency and time reassignment of Fourier transform data. These methods are then compared with an adapted version of an existing discrimination method, both in terms of their effectiveness and their computational cost.
