Abstract：By analyzing algorithms available for variable step size least mean square(LMS) adaptive filter, a new modified LMS adaptive filtering algorithm with variable step size is proposed, along with performance analysis based on different parameters. Compared with the existing algorithms through the simulation, the proposed algorithm has faster convergence speed and smaller steady state error.
Key words：adaptive filter; variable step size; least mean square(LMS)
