摘要 研究了由Wiener-amalgam空间中的函数φ生成的整平移不变子空间V 2(φ)的采样集X问题,并运用生成子φ的连续模(oscillation)刻画了构成V 2(φ)的采样集X的一个充分条件. The problem of the sampling sets X of shift-invariant subspace V^2(Ф) generated by Ф is researched in this paper, where Ф belongs to Wiener-amalgam space. A sufficient condition of sampling sets of V^2 (Ф) by means of oscillation of generator Ф is obtained.
