Cette étude montre une méthode de simulation rapide pour les turbocodes sur un canal de bruit additif de classe A blanche (AWAN). La réduction du temps d'estimation est obtenue en appliquant un échantillonnage par importance (IS) qui est l'une des méthodes de simulation de réduction de la variance. Afin d'adapter le canal AWAN, nous proposons une méthode de conception d'une fonction de densité de probabilité (PDF) de simulation utilisée en SI. Le PDF de simulation proposé est lié à la contrainte Bhattacharyya d'évaluer une zone plus large de l'espace du signal que la méthode conventionnelle. Étant donné que la méthode de traduction moyenne, qui est une méthode de conception conventionnelle du PDF de simulation utilisée dans IS, est optimisée pour un canal de bruit blanc gaussien additif, le temps d'évaluation des performances d'erreur des turbocodes sur le canal AWAN ne peut pas être réduit. Pour évaluer un BER de 10-8, le temps de simulation de la méthode proposée peut être réduit à 1/104 sous la même condition de précision que la méthode traditionnelle de simulation de Monte Carlo.

Abstract: This study shows a fast simulation method for turbo codes over an additive white class A noise (AWAN) channel. The reduction of the estimation time is achieved by applying importance sampling (IS) which is one of the variance reduction simulation methods. In order to adapt the AWAN channel, we propose a design method of a simulation probability density function (PDF) utilized in IS. The proposed simulation PDF is related to the Bhattacharyya bound to evaluate wider area of the signal space than the conventional method. Since the mean translation method, which is a conventional design method of the simulation PDF used in IS, is optimized for an additive white Gaussian noise channel, the evaluation time of the error performance of turbo codes over the AWAN channel can not be reduced. To evaluate BER of 10-8, the simulation time of the proposed method can be reduced to 1/104 under the condition of the same accuracy of the traditional Monte Carlo simulation method.
