Abstract :
A recursive least square (RLS) based complex adaptive notch filter (ANF) using the Steiglitz-McBride (SM) method is proposed to suppress the radio frequency interference (RFI) in very-high-speed digital subscriber line (VDSL) systems. The proposed RLS-SM ANF converges fast and requires less computational complexity than the existing direct form constrained ANF using a recursive prediction error (RPE) algorithm. The proposed algorithm is specially advantageous when dealing with multiple RFI´s
