MATLAB program for SVD that enables noise removal operations on one-dimensional signals, featuring matrix decomposition and signal processing capabilities
Detailed Documentation
Singular Value Decomposition (SVD) is a mathematical method widely used in matrix decomposition and signal processing applications. MATLAB provides a dedicated svd function that facilitates noise removal operations on one-dimensional signals. The implementation works by decomposing the signal matrix into singular values, where dominant singular values represent the principal signal components while smaller values typically correspond to noise. The algorithm involves constructing a Hankel matrix from the input signal, performing SVD using [U,S,V] = svd(A), and then reconstructing the signal by retaining only the significant singular values. Key functions include threshold selection for singular value retention and matrix reconstruction techniques. This program proves particularly valuable in practical applications for enhancing signal processing accuracy and effectiveness by separating signal components from noise interference.
