多通道噪声采样信号重构

Signal reconstruction from noisy multichannel samples

Dong Cheng, Xiaoxiao Hu, Kit Ian Kou

摘要:

本文研究了多通道采样信号在噪声存在的情况下的信号重构问题。观察到,如果样本不精确,则严格执行多通道内插是不合适的。因此,合理的光顺和正则化校正是必不可少的。在本文中,我们提出了几种不同的平滑和正则化原则下的信号重建的方法从噪声多通道样本。我们比较这些信号重建方法在理论和实验上在各种情况下。为了证明所提出方法的有效性,提供了这些方法的概率解释和误差分析。最后,给出了数值模拟结果,并给出了一些使用方法的指导原则.

英文摘要:

We consider the signal reconstruction problem under the case of the signals sampled in the multichannel way and with the presence of noise. Observing that if the samples are inexact, the rigorous enforcement of multichannel interpolation is inappropriate. Thus the reasonable smoothing and regularized corrections are indispensable. In this paper, we propose several alternative methods for the signal reconstruction from the noisy multichannel samples under different smoothing and regularization principles. We compare these signal reconstruction methods theoretically and experimentally in the various situations. To demonstrate the effectiveness of the proposed methods, the probability interpretation and the error analysis for these methods are provided. Additionally, the numerical simulations as well as some guidelines to use the methods are also presented.
