Abstract:Denote by B2σ,p(1 < p < ") the bandlimited class p-integrable functions whose Fourier transform is supported in the interval [-?, ?]. It is shown that a function in B2σ,pcan be reconstructed in Lp(R) by its sampling sequences {f(k?/?)}k∈Z and{f 2(k?/?)}k∈Z using the Hermite cardinal interpolation. Moreover, it will be shown that if f belongs to Lpr(R), 1 < p < ∞, then the exact order of its aliasing error can be determined.
