Implantation d'Algorithms Rapides sur des Processeurs de Traitement du Signal (Implantation of Fast Algorithms in Signal Processing Processors)

摘要

The problems of the implementation of fast recursive least square algorithms are studied, considering a system integrated with transversal form, adaptive filtering, and linear prediction. It is demonstrated that these algorithms differ only in the values of the intermediate variables. Relations to optimize the pseudo-likelihood variable are proposed for the normalized and nonnormalized cases. A procedure for the implementation with fixed point arithmetics is described.
