FFT reconstruction of signals from MIMO sampled data
Dong Cheng, Xiaoxiao Hu, Kit Ian Kou
This paper introduces an innovative approach for signal reconstruction using data acquired through multi-input-multi-output (MIMO) sampling. First, we show that it is possible to p…
Signal reconstruction from noisy multichannel samples
Dong Cheng, Xiaoxiao Hu, Kit Ian Kou
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 inexac…
FFT Multichannel Interpolation and Application to Image Super-resolution
Dong Cheng, Kit Ian Kou
This paper presents an innovative set of tools to support a methodology for the multichannel interpolation (MCI) of a discrete signal. It is shown that a bandlimited signal can…
Uncertainty Principle for Measurable Sets and Signal Recovery in Quaternion Domains
Kit Ian Kou, Yan Yang, Cuiming Zou
The classical uncertainty principle of harmonic analysis states that a nontrivial function and its Fourier transform cannot both be sharply localized. It plays an important role in…
