| Abstract: | A pseudo-random signal sequence added to the input of error channel,this article attempts to achieve line identification to ensure that the Filtered-XLMS algorithm converges rapidly.A simulation model was established through MATLAB.Comparing the simulation results with the data from SY156FM motorcycle engine,this article concludes that this approach has the advantages of fast convergence,strong real-time,good identification,producing the desired effect of noise reduction. |
