Study on Adaptive Filtering Algorithm in the Echo Cancellation in Mine

To solve the problem of echo cancellation in mine, the adaptive filtering LMS algorithm is used, firstly, the advantages and disadvantages of the adaptive filtering algorithm are analyzed, then the existing problems of LMS algorithm are improved, and the convergence, anti-noise and stability of the algorithm are analyzed theoretically, in the simulation experiment, the acoustic samples collected in mine are analyzed from aspects of convergence, calculation and output, which shows that the proposed algorithm has a certain effect on the echo cancellation.
