A method of using a digital signal processor to calculate the conventional normalized least mean square (NLMS) adaptation algorithm without using a division operation. The method involves estimation, multiplication and comparison steps with appropriate adjustment in the estimation to reach the solution. The advantage of the method is that the more complex instruction cycles required for the division operation are avoided.
Procédé d'utilisation d'un processeur de signaux numériques afin de calculer l'algorithme d'adaptation à moyenne quadratique minimale normalisée (NLMS) sans effectuer d'opération de division. Ce procédé consiste en des étapes d'estimation, de multiplication et de comparaison, l'estimation étant ajustée de façon appropriée afin d'atteindre la solution. Ce procédé permet avantageusement d'éviter les cycles d'instruction plus complexes nécessaires à l'opération de division.
