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.
