Sažetak
Time-frequency distributions represent an efficient tool in the analyzing and processing of nonstationary signals. Some characteristics of nonstationary signals (such as frequency modulation or the property of multi-components) result in the appearance of undesirable interference terms (cross-terms) which do not exist in an ideal time-frequency representation. In this paper, several mathematical operations are used in order to enhance the quality of time-frequency distributions representation. Mathematical operations applied to the spectrogram have led to an improvement in the concentration of the signal energy about its instantaneous frequency. The multiplication of the Wigner-Ville distribution by the Pseudo Wigner-Ville distribution, on the other hand, is proposed as a method for cross-terms suppression, and its performance is numerically compared to that of the Wigner-Ville distribution masked by the spectrogram.
