A Variable Evolutionary Coefficients Adaptive Noise Cancellation Algorithm
Factors of fitness function using the reciprocal of the average energy of the output signal, constant cloning and mating coefficients all restrict the convergence and noise cancellation performances of the traditional evolutionary adaptive noise cancellation algorithm. In this paper, the variable coefficients evolutionary adaptive noise cancellation algorithm using dynamic fitness function is proposed. The mating coefficient is related to evolutionary generation and the cloning coefficient is determined by evolutionary generation and fitness value, and a dynamic fitness function is also employed. Results from simulation case and test datasets show that the proposed algorithm exhibits better convergence and noise cancellation performances than other similar algorithms.
