Application of Composite Dictionary Multi-Atom Matching in Gear Fault Diagnosis

Application of Composite Dictionary Multi-Atom Matching in Gear Fault Diagnosis

The sparse decomposition based on matching pursuit is an adaptive sparse expression method for signals. This paper proposes an idea concerning a composite dictionary multi-atom matching decomposition and reconstruction algorithm, and the introduction of threshold de-noising in the reconstruction alg...
