摘　　要：A new statistical analysis model is proposed to analyze the Affine pro jection algorithm with direction error(AP-DE).Four assumptions are made,which are based on the direction vector for the AP-DE algorithm.Under these assumptions,deterministic recursive equations for the weight error and for the mean-square error are derived.We also analyze the steady-state behavior of the AP-DE algorithm.Simulation results are provided to corroborate the analytical results.A new statistical analysis model is proposed to analyze the Affine pro jection algorithm with direction error（AP-DE）.Four assumptions are made,which are based on the direction vector for the AP-DE algorithm.Under these assumptions,deterministic recursive equations for the weight error and for the mean-square error are derived.We also analyze the steady-state behavior of the AP-DE algorithm.Simulation results are provided to corroborate the analytical results.
