On Uncertainty Principle for the Linear Canonical Transform of Complex Signals

This correspondence derives the uncertainty principle bounds for the linear canonical transform (LCT) of a complex signal. The derived bounds are sharper than that of the published papers and they are related with the phase and the amplitude of the complex signal. An example is given to verify the r...

Zusammenfassung:This correspondence derives the uncertainty principle bounds for the linear canonical transform (LCT) of a complex signal. The derived bounds are sharper than that of the published papers and they are related with the phase and the amplitude of the complex signal. An example is given to verify the result.
