Improved Affine Projection Sign Algorithm for Sparse System Identification

Proposed is a novel affine projection sign algorithm with L-0-norm cost to improve the convergence rate in a sparse system. The proposed algorithm is robust to impulsive noise due to L-1-norm minimisation. It also ensures improved performance in terms of convergence rate owing to the L-0-norm cost. The simulation results demonstrate that the proposed algorithm improves the filter performance of sparse system identification.X1122sciescopu
