Comparative analysis of algorithms for sparse wavelet decomposition of vibration signals
Abstract
Five modifications of the sparse wavelet decomposition algorithm for automatic analysis of the vibration signals waveform were proposed in the article. A comparative analysis of the developed modifications was carried out and the best one was selected according to the criterion of maximizing the rate of signal decomposition and minimizing the approximation error.
