  • Abstract
    A new weighted exact least squares lattice algorithm for adaptive noise cancellation is developed. In addition to the forgetting factor, an independent weighting factor is included in the performance criterion to be minimized. Such a weighting scheme can be used to improve noise cancellation performance. The authors explore this by comparing the features of the weighted and nonweighted algorithms. Using simulations, they demonstrate the superior performance of the weighted exact least squares lattice algorithm.
