S.Arunkumar, P.Parthiban, S.Aravind Kumar

The present work describes the implementation of a better convergence adaptive filter through the least mean square algorithm for both sinusoidal and audio denoising i.e., to obtain an original sinusoidal signal and the audio signal back from the same which was corrupted using a random noise .The application had been performed over an FPGA (field-programmable gate arrays) Spartan 3 from Xilinx, using Matlab and System Generator. Initially the algorithm was simulated and tested on Matlab and a Simulink block for the algorithm was created using the AccelDSP software and the same was implemented on a SPARTAN -3 XC3S500 FG320 -5 for the hardware implementation of the algorithm.
