Title (EN) ADAPTIVE ARRAY APPARATUS
(FR) DISPOSITIF A RESEAU ADAPTATIF
Abstract: front page image
(EN)The control unit (50) calculates weighting factors for one symbol out of every k symbols. During this calculation, the control unit (50) calculates weighting factors for respective inphase and quadrature components of the symbol stored in every I and Q buffers based on the inphase and quadrature components. The control unit (50) also interpolates weighting factors for the remaining k-l symbols. During this interpolation, the control unit (50) uses the weighting factors that are currently calculated and the weighting factors that have been previously calculated and are stored in the W buffer (51). The calculated and interpolated weighting factors are used for forming a directivity pattern.
(FR)Une unité de commande (50) calcule des facteurs de pondération d'un symbole tous les k symboles. Pendant le calcul, l'unité de commande (50) calcule simultanément les facteurs de pondération des composantes en phase et en quadrature qui sont stockés respectivement dans des tampons I et Q à cet effet. Pendant cette interpolation, l'unité de commande utilise les facteurs de pondération venant d'être calculés ainsi que les facteurs de pondération calculés antérieurement stockés dans le tampon W (51). Les facteurs de pondération calculés et interpolés constituent un motif de directivité.
