  • Abstract
    A fast algorithm for the Gabor representation for transient signals is presented, via the fast DCT-based real-valued Gabor transforms proposed in our previous papers for joint time-frequency analysis of nonstationary signals. The proposed algorithm is capable of separating transient signals with different frequencies, various arrival times, and additive white noises. Numerical examples are given to demonstrate the efficiency of the algorithm.
