摘要

提出了一种基于Chebyshev非均匀采样的Chebyshev型插值函数(CTIF)，并讨论了该函数的一些重要性质。结果表明，利用CTIF可以清晰地描述非均匀样本的信号重构概念。本文还讨论了该方法的时域结构和采用收缩阵列结构的变换域结构两种实现方案。该方案具有简单、规则、重构速度快等优点，适用于数据压缩。

Systolic array implementations for Chebyshev nonuniform sampling

A Chebyshev-type interpolation function (CTIF) based on Chebyshev nonuniform sampling is developed, and some important properties of the CTIF are discussed. It has been demonstrated that the concept of signal reconstruction from the nonuniform samples can be described clearly by using the CTIF. Two implementation schemes, a time domain structure and a transformed domain structure using systolic array architecture for this method, are also discussed. The schemes have the advantages of simplicity, regularity, and fast reconstruction, and they are suitable for data compression.<>
