Affine Projection Adaptive Filter

The examples provided here use a sinusoid signal mixed with Gaussian noise.

Affine Projection Adaptive Filter

The parameters for this filter are as follows:

• Window Size ⇨ 7

Code

int order = 3;
double mu = 0.25;
double eps = 0.001;
int length = 20;

AP filt1 = new AP(length, order, mu, eps, AP.WeightsFillMethod.ZEROS); // Initialising weights to zero
filt1.filter(desired, signal); // Weights are adapted so that the input signal can be modified to the desired signal
