Active noise control of the nonlinear noise processes uses nonlinear control structures such as Volterra filter or different kinds of neural networks. Filtered-s LMS (FSLMS) algorithm is a recently proposed algorithm, which uses functional link artificial neural network as its control structure. It is seen that filtered-s LMS algorithm outperforms the ANC algorithms like FXLMS and also the Volterra filtered-x LMS (VFXLMS) under higher order nonlinearity case. It is also seen that the nonlinear ANC algorithms like FSLMS or VFXLMS algorithms involves higher computational complexity than the linear ANC algorithm such as FXLMS algorithm. In this paper, Hartley transform is used to implement exactly the same FSLMS algorithm involving lesser number of computations.
