Research on noise reduction algorithm based on packet digital average and correlation analysis

摘要

In order to improve the signal-to-noise ratio(SNR) of the noise-contaminated signal and speed up the calculation speed. Firstly, digital average and correlation analysis two traditional methods is introduced in this paper, and then a new fusion algorithm method based on packet digital average and correlation analysis is proposed. Furthermore, simulations based on MATLAB of digital average, correlation analysis and fusion algorithm are used to verify the feasibility of fusion algorithm. The results show that fusion algorithm based on packet digital average and correlation analysis is better than digital average method and correlation analysis method in calculation speed and noise reduction effect for the same input SNR.
