Resource Overview
A program for calculating phase differences using cross-correlation method with wavelet-based signal denoising for enhanced accuracy in signal analysis.
Detailed Documentation
This implementation calculates the phase difference between two signals using the cross-correlation method. The process begins with wavelet-based denoising to enhance signal clarity and accuracy by removing noise components. Following signal preprocessing, the cross-correlation algorithm detects precise phase differences by measuring the time shift between corresponding signal features.
Key implementation aspects include:
- Applying discrete wavelet transform (DWT) for multi-resolution noise reduction
- Computing cross-correlation using efficient FFT-based convolution
- Identifying peak correlation positions to determine phase offsets
- Converting time delays to phase differences using signal frequency information
This methodology provides reliable phase difference measurements, supporting advanced signal analysis and research applications with improved result accuracy and detailed signal relationship insights.
