Band-limited Signal Concentration in Time-frequency
This paper studies signal concentration in timefrequency using the general constrained variational method of Franks. We apply this method to formulate the minimum fourthmoment time-duration measure in the time interval [-T/2, T/2] for band-limited signals. An orthonormal basis of band-limited functions with the minimum fourth-moment time-duration measure is obtained. Comparing our optimal band-limited signals with Gabor's function with the minimum second-moment timeduration measure, simulation...[Show more]
