摘要：In this paper, the authors have provided a brief review of the recent advances in the Shannon sampling theory. In particular, they discuss the work related to 1-D signal reconstruction involving the samples taken below the Nyquist rate using nonlinear/time-variant systems. The extensions of the sampling theorems to the fractional Fourier and Linear canonical transform domains are also discussed.
