Title (EN) ADAPTIVE BEAM-STEERING METHODS TO MAXIMIZE WIRELESS LINK BUDGET AND REDUCE DELAY-SPREAD USING MULTIPLE TRANSMIT AND RECEIVE ANTENNAS
(FR) PROCEDES D'ORIENTATION ADAPTATIVE DE FAISCEAUX PERMETTANT DE MAXIMISER LE BUDGET DE LA LIAISON SANS FIL ET DIMINUER LE TEMPS DE PROPAGATION A L'AIDE D'ANTENNES MULTIPLES D'EMISSION ET DE RECEPTION
Abstract: front page image
(EN)A method and apparatus for adaptive beam-steering are disclosed. In one embodiment, the method comprises performing adaptive beam steering using multiple transmit and receive antennas, including iteratively performing a pair of training sequences, wherein the pair of training sequences includes estimating a transmitter antenna-array weight vector and a receiver antenna-array weight vector.
(FR)La présente invention concerne un procédé et un appareil destinés à l'orientation adaptative de faisceaux. Dans un mode de réalisation, le procédé comprend la réalisation d'orientation adaptive de faisceaux à l'aide d'antennes multiples d'émission et de réception, dans lequel la paire de séquences de formation comprend l'estimation d'un vecteur de poids d'un réseau d'antennes d'émission et un vecteur de poids de réseau d'antennes de réception.
