Design of Systolic architecture for various adaptive filters for noise cancellation

An adaptive filter plays an important role in noise cancellation application. In this paper, a Systolic architecture is proposed in Recursive Least Square (RLS) adaptive filter structure and Affine Projection (AP) adaptive filter structure for denoising Electrocardiogram (ECG) and speech signal effectively. The proposed architecture is designed to improve the speed of the process. The above filter structures are simulated in Xilinx System generator and also in MATLAB Simulink environment and performance of the RLS adaptive algorithm and AP adaptive algorithm is measured by Signal to Noise (SNR) ratio.
