Nonuniform sampling of bandlimited functions

초록

In this correspondence, we show that a function in the Bernstein class BP (1 <= p <= infinity) can be reconstructed in the Lagrange interpolation form with sampling points {t(n)} satisfying vertical bar t(n) - n vertical bar <= d and [4d] additional points, where d is any nonnegative real number that is not necessarily less than 1/4. Here, [x] denotes the integer part of x.
