Abstract A modified adaptive filter algorithm of smooth pseudo LMS(SPLMS) based on pseudo LMS(PLMS) is presented in this paper. Besides having advantages of PLMS, it has faster beginning convergence rate, lower misadjustment of weight, and better robustness aganist noise and disturbance. The theoretical analysis is confirmed by computer simulation results.
