广义Sinc函数重构非带限信号的采样误差分析及性质

Youfa Li, Qiuhui Chen, Tao Qian, Yi Wang

摘要:

近年来,利用广义sinc函数对各种非带限信号进行了理想重构。因此,完美的重建采样公式已建立使用这种广义sinc函数。本文研究了自适应截断方案重构非带限信号的误差。此外,当样本中存在噪声时,还给出了与重构信号相关的误差的期望和方差的估计。最后讨论了非带限信号空间中函数的再生性和Sobolev光滑性。

英文摘要:

Recently efforts have been made to use generalized sinc functions to perfectly reconstruct various kinds of non-bandlimited signals. As a consequence, perfect reconstruction sampling formulas have been established using such generalized sinc functions. This article studies the error of the reconstructed non-bandlimited signal when an adaptive truncation scheme is employed. Further, when there are noises present in the samples, estimation on the expectation and variance of the error pertinent to the reconstructed signal is also given. Finally discussed are the reproducing properties and the Sobolev smoothness of functions in the space of non-bandlimited signals that admits such a sampling formula.
