Wavelet Threshold Denoising with Code Implementation Details - Comprehensive Comparison Between Soft Thresholding and Hard Thresholding Methods in Digital Signal Processing
Speech signal denoising implementation in MATLAB environment, performing wavelet transform on noisy speech signals, applying threshold-based denoising principles, and reconstructing enhanced speech signals through inverse transformation with detailed algorithm explanation.
The latest program for 1D signal denoising using Empirical Mode Decomposition (EMD) incorporates three advanced denoising techniques: 1) Direct wavelet thresholding with hard thresholding implementation; 2) EMD-specific threshold denoising leveraging intrinsic mode function characteristics; 3) Shift-invariant denoising applied after EMD decomposition for enhanced performance. The program implements these methods through MATLAB functions including emd() for decomposition, wthresh() for threshold operations, and custom algorithms for mode alignment in shift-invariant processing.
