摘要：
Reconstruction method for reconstructing a first signal (x(t)) regularly sampled at a sub-Nyquist rate, comprising the step of retrieving from the regularly spaced sampled values (y s [n], y(nT)) a set of weights (c n , c nr , c k ) and shifts (t n , t k ) with which said first signal (x(t) can be reconstructed. The reconstructed signal (x(t) can be represented as a sequence of known functions (γ(t) weighted by the weights (c k ) and shifted by the shifts (t k ). The sampling rate is at least equal to the rate of innovation (ρ) of the first signal (x(t)).
摘要（中）：
一种用于重建以次奈奎斯特速率规则采样的第一信号（x（t））的重建方法，包括从规则间隔的采样值（y> s <[n]，y（nT））中检索一组 可以重构所述第一信号（x（t））的权重（c> n <，c> nr <，c> k <）并移位（t> n <，t> k < t）可以表示为由权重（c> k <）加权并被移位（t> k <）的已知函数（gamma（t））的序列，采样率至少等于创新速率 （x（t））的（rho）。
