Abstract

Proposed is a variable step-size affine projection sign algorithm (APSA) based on the minimisation of mean-square deviation. Because the proposed algorithm calculates the optimum step size in every iteration, it ensures an improved performance in terms of convergence rate and misalignment, compared to conventional APSAs. The proposed algorithm is tested in a system identification scenario that includes impulsive noise.
