Simultaneous Greedy Analysis Pursuit for Compressive Sensing of Multi-Channel ECG Signals
Yurrit Avonds, Yipeng Liu, Sabine Van Huffel
This paper addresses compressive sensing for multi-channel ECG. Compared to the traditional sparse signal recovery approach which decomposes the signal into the product of a dictio…

Robust Cosparse Greedy Signal Reconstruction for Compressive Sensing with Multiplicative and Additive Noise
Yurrit Avonds, Yipeng Liu, Sabine Van Huffel
Greedy algorithms are popular in compressive sensing for their high computational efficiency. But the performance of current greedy algorithms can be degenerated seriously by noise…
