Variable Normalized sub-band adaptive filter and Variable Step Size Selective Partial Update Affine Projection Algorithm for Acoustic Echo Cancellation Applications

In this paper, we apply the family of the variable step size selective partial update APA (VSS-SPUAPA) and Normalized Subband Adaptive Filter (NSAF) and variable step size Normalized Subband Adaptive Filter (VSS-NSAF). The simulation results show the good performance of the VSS-NSAF algorithm at high convergence rate and low level of mean square error (MSE) .Also, this paper compares the computational complexity of the VSS-NSAF and NSAF with VSS-SPU-APA, Which demonstrates the low computational complexity of the algorithm proposed compared to other algorithms in the application of echo cancelation
