Abstract :
A signal-dependent tapering function which is able to reduce time-domain cross terms for the class of impulsive signals is introduced. The reverse-correlation function magnitude is constrained to suppress increases away from the origin. In combination with the cone-shaped kernel approach, the resulting time-frequency distribution (TFD) demonstrates a reduction in both the time- and frequency-domain cross terms
