Adaptive Filtering Routine: Adaptive Window Sliding Filter Implementation in MATLAB – Comparison of Original Signal, Fixed Window Filtering, and Adaptive Window Filtering

Adaptive Filtering Routine: Adaptive Window Sliding Filter Implementation in MATLAB - Comparison of Original Signal, Fixed Window Filtering, and Adaptive Window Filtering

The program implements three types of processing and comparison for one-dimensional time series signals: the original signal, fixed window sliding filtering, and adaptive window sliding filtering based on local variance judgment. The purpose is to simulate a real noise environment and examine the impact of different window strategies on signal smoothing effects, fidelity, and error … Read more
