N2 - In recent years, more attention has been paid to the performance of algorithms in active noise control. Compared with the filtered-x LMS algorithm based on stochastic gradient descent, the filtered-x RLS algorithm has a faster convergence speed and better tracking performance at the cost of high computational complexity. In order to reduce the computation, the fast transversal filter algorithm can be used in ANC systems. In this paper, two simplified multichannel filtered-x FTF algorithms are presented, and the convergence speed and noise reduction performance of different multichannel algorithms are simulated and compared. The simulation results demonstrate the efficiency of the proposed algorithms for both stationary white noise and time-varying actual measured noise.
