Title (EN) ADAPTIVE INTERPOLATOR FOR CHANNEL ESTIMATION
(FR) INTERPOLATEUR ADAPTATIF POUR ESTIMATION DE CANAL
Abstract: front page image
(EN)A method for channel estimation in a wireless communication system includes the following steps. Channel transfer function is computed at continual and scattered pilot cells using transmitted and received signals at the continual and scattered pilot cells. Time-domain adaptive interpolation is performed to obtain channel transfer function at non-pilot cells of the scattered pilot tones using the channel transfer function computed at continual and scattered pilot cells. Frequency-domain adaptive interpolation is performed to obtain channel transfer function at non-pilot cells of non-pilot tones using the channel transfer function computed at continual and scattered pilot cells.
(FR)Procédé d'estimation de canal dans un système de communications englobant les opérations suivantes. Calcul de la fonction de transfert du canal dans des cellules pilotes continues ou dispersées au moyen de signaux reçus et émis au niveau desdites cellules. On exécute une interpolation adaptative du domaine temps pour obtenir la fonction de transfert de canal dans des cellules non pilotes de tonalité pilotes dispersées au moyen de la fonction de transfert de canal calculé au niveau des cellules pilotes continues et dispersées. On exécute une interpolation adaptative du domaine temps pour obtenir la fonction de transfert de canal dans des cellules non pilotes de tonalités non pilotes au moyen de la fonction de transfert de canal calculée au niveau des cellules pilotes continues et dispersées.
