Abstract

It’s well known, biased estimation can effectively reduce the steady-state mean-square error (MSE), as for system identification with a low signal-to-noise ratio (SNR).A new biased normalized least-mean-squares (NLMS) algorithm is proposed in this paper. In the proposed algorithm the optimal solution is deduced on the basis of maximizing the decrease of the mean square deviation (MSD). To facilitate practical application approximation and parameter choice guidelines are provided for the new algorithm. The proposed algorithm is confirmed by simulations to obtain both a small steady-state excess MSE (EMSE) and a fast convergence rate, and to outperform the existing convex combination of two NLMS filters (CNLMS) algorithm. Steady state performance and transient performance analyses are provided to interpret the simulation results.
