Wavelet Analysis-Based Signal Energy Feature Extraction Method

Wavelet analysis-based signal energy feature extraction method for pattern recognition, with MATLAB source code implementation including decomposition, energy calculation, and feature vector construction algorithms

MATLAB Code Implementation for Signal-to-Noise Ratio (SNR)

Signal-to-Noise Ratio (SNR), calculated as signal energy divided by noise power, helps analyze signal components; implementation involves calculating signal and noise powers using MATLAB functions like mean(), var(), or bandpower()
