Robust EP latency change estimation algorithm under time-variant impulsive noise environments

Alpha stable noises in evoked potentials (EPs) are usually time-variant, which result in a degradation in performance for direct least mean p-norm (DLMP) algorithm. This paper proposed dynamic parameter estimation method and modified DLMP algorithm. The robustness of the proposed algorithm is demonstrated through computer simulations under both time-invariant and time-variant noise environments.
