Robust S-transform based on L-DFT

September 1, 2011

Time-frequency representations of signals obtained by the S-transform can be very sensitive to the presence of alpha-stable noise. An algorithm for the robust S-transform is introduced. The proposed scheme is based on the L-DFT. The results of conducted numerical analysis show a significantly enhanced performance of the proposed scheme compared to the standard S-transform.
