Abstract :
A modified method for estimating frequencies of short-time-recorded superimposed sinusoidal signals is presented. This method applies rank reduction and regularisation to the Tufts-Kumaresan (TK) method by modifying the Sano matrix inversion method for short-time-recorded data. This method needs no a priori information on signals
