| 520 | 3 | |a Let $$\phi \in W(C,\ell ^1)$$ ϕ ∈ W ( C , ℓ 1 ) such that $$\{\tau _n\phi :n\in \mathbb {Z}^d\}$$ { τ n ϕ : n ∈ Z d } forms a Riesz basis for $$V(\phi )$$ V ( ϕ ) . It is shown that $$\mathbb {Z}^d$$ Z d is a stable set of sampling for $$V(\phi )$$ V ( ϕ ) if and only if $$\Phi ^\dagger (x)\ne 0$$ Φ † ( x ) ≠ 0 , for every $$x\in \mathbb {T}^d$$ x ∈ T d , where $$\Phi ^{\dagger }(x):=\sum _{n\in \mathbb {Z}^d}\phi (n)e^{2\pi in\cdot x},~~ x\in \mathbb {T}^d$$ Φ † ( x ) : = ∑ n ∈ Z d ϕ ( n ) e 2 π i n · x , x ∈ T d . Sampling formulae are provided for reconstructing a function $$f\in V(\phi )$$ f ∈ V ( ϕ ) from uniform samples using Zak transform and complex analytic technique. The problem of sampling and reconstruction is discussed in the case of irregular samples also. The theory is illustrated with some examples, and numerical implementation for reconstruction of a function from its nonuniform samples is provided using MATLAB. | |
