Abstract

A modified variable step‐size affine projection sign algorithm (MVSS‐APSA) is proposed. Considering the effect of the noise on the steady‐state error, the first moment estimation of the noise is utilised to modify the variable step‐size update. The test on system identifications under an impulsive noise environment shows that the proposed MVSS‐APSA has lower steady‐state misalignment than the VSS‐APSA.
