I recommend the following article which includes a C-subprogramm for a
smoothed version (for cross-term suppression) of the Wigner-Distribution:

Wood/Buda/Barry: "Time-Frequency Transforms: A New Approach to First Heart
Sound Frequency Dynamics", IEEE Trans. on  Biomed. Eng., Vol.39, No.7,
July 1992, pp.730-740
