Alternate Derivative Sampling Expansion

초록/요약

Using two-channel method, we show that {e^(2inx) : n ∈ Z} is a Riesz basis. And using this Riesz basis, we obtain a sampling expansion for f ∈ B with the sampling data {f(2n), f'(2n + α) : n ∈ Z}, where α∈(0, 1)U(1,2) and B is the space of bandlimited functions with bandlimit π.
