Detailed Documentation

The MP-based signal sparse decomposition algorithm is a computationally efficient and easily implementable method widely adopted across various technical fields. Its core strength lies in handling signal sparsity through iterative atom selection from predefined dictionaries, typically implemented using orthogonal matching pursuit (OMP) or similar variants. Key algorithmic advantages include effective preservation of critical signal information during decomposition and low computational complexity. The implementation commonly involves steps like residual calculation, inner-product-based atom selection, and coefficient updates through least-squares solutions. Due to its elegant design and robust performance, this algorithm serves as a fundamental tool in image processing, speech recognition, and other signal processing applications. Its versatility and operational efficiency make it indispensable in both scientific research and practical engineering solutions.
