Normalised least‐mean‐square algorithm for adaptive filtering of impulsive measurement noises and noisy inputs
A bias‐compensated error‐modified normalised least‐mean‐square algorithm is proposed.
The proposed algorithm employs nonlinearity to improve robustness against impulsive
measurement noise, and introduces an unbiasedness criterion to eliminate the bias due to
noisy inputs in an impulsive measurement noise environment. To eliminate the bias
properly, a new estimation method for the input noise variance is also derived. Simulations
in a system identification context show that the proposed algorithm outperforms the other …

To eliminate the bias properly, a new estimation method for the input noise variance is also derived. Simulations in a system identification context show that the proposed algorithm outperforms the other algorithms because of the improved adaptability to impulsive measurement noise and input noise in the system.
