In today's data processing field, iterative compressed sensing reconstruction algorithms are becoming increasingly popular. These algorithms help solve the problem of recovering original information from limited data samples. The fundamental concept involves sparse signal representation during data acquisition, followed by iterative approximation of the original signal through compressed sensing techniques to achieve reconstruction. Implementation typically involves optimization functions like l1-minimization using convex optimization packages (e.g., CVX in MATLAB or scikit-learn in Python), where each iteration refines the signal estimate through gradient descent or proximal methods. This algorithm has gained extensive applications in image processing, signal processing, and communication fields, becoming a key research focus for many investigators studying sparse signal recovery and computational efficiency.
