Abstract :

This paper describes the concept of adaptive noise cancelling. The noise cancellation using the Recursive Least Squares (RLS) to remove the noise from an input signal. The RLS adaptive filter uses the reference signal on the Input port and the desired signal on the desired port to automatically match the filter response in the Noise Filter block. The filtered noise should be completely subtracted from the "noisy signal” of the input Sine wave & noise input signal, and the "Error Signal" should contain only the original signal. Finally, the functions of field programmable gate array based system structure for adaptive noise canceller based on RLS algorithm are synthesized, simulated, and implemented on Xilinx XC3s200 field programmable gate array using Xilinx ISE tool.
