Abstract :
A new variable-step-size LMS algorithm is proposed, and it performance is analyzed. Simulation results indicate that the performance is superior to that of existing VSS algorithm and NLMS algorithm. The proposed algorithm is then applied to adaptive noise jamming cancellation system; the computer simulation shows superior performance over the NLMS algorithm and MVSS algorithm.
