Step 1: initialize parameters and the initial value of the adaptive filter weighting coefficient . The order and step value are set as and , respectively

Step 2: calculate the output result of the filter estimation

Step 3: calculate the error of the filter

Step 4: the filter weighting coefficient is updated to

Step 5: repeat steps 2–4 above until the weight coefficient of the filter approaches the best filter
