Reconstruction of Signal using Interpolation

Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next sampling...

Compressive sensing (CS) can reconstruct signals from fewer measurements. This new framework leverages multiple signal structures for improved biomedical signal recovery accuracy.

Area of Science:

Biomedical Engineering
Signal Processing
Applied Mathematics

Background:

Compressive sensing (CS) reconstructs signals from sub-Nyquist measurements.
Classical CS methods primarily exploit sparsity in a single domain.
Biomedical signals often possess complex structures like multi-sparsity or low-rank properties.

Purpose of the Study:

To develop a novel framework for compressive sensing that exploits multiple signal structures.
To enhance the accuracy of biomedical signal reconstruction by utilizing inherent signal properties.

Main Methods:

Formulated a new convex programming problem incorporating multiple structure-inducing constraints.
Integrated linear measurement fitting constraints within the optimization problem.
