Abstract :
A NLMS-like (Normalized Least Mean Square) adaptive filtering algorithm with decorrelation ability is proposed. We not only prove the convergence of the new algorithm, but also analyze its decorrelation ability. Simulation shows that it has a better effect than Benesty (1996) and Sankran (1999) when applied to stereophonic acoustic echo cancellation
