Reversible Joint Hilbert and Linear Canonical Transform Without Distortion [PDF]

IEEE Transactions on Signal Processing, Volume 61, Issue 19, Oct.1, 2013, 2017
Generalized analytic signal associated with the linear canonical transform (LCT) was proposed recently by Fu and Li ["Generalized Analytic Signal Associated With Linear Canonical Transform," Opt. Commun., vol. 281, pp. 1468-1472, 2008]. However, most real signals, especially for baseband real signals, cannot be perfectly recovered from their ...
