Title (EN) TECHNIQUE FOR DETERMINING AN ANGLE OF ARRIVAL IN A COMMUNICATION SYSTEM
(FR) TECHNIQUE DE DÉTERMINATION D'UN ANGLE D'ARRIVÉE DANS UN SYSTÈME DE COMMUNICATION
Abstract: front page image
(EN)Embodiments of a circuit are described. In this circuit, a transmit circuit provides signals to antenna elements during an acquisition mode, where a given signal to a given antenna element includes at least two frequency components having associated phases, and where the phase of a given frequency component in the given signal is different from phases of the given frequency component for the other antenna elements. Moreover, an output node couples the transmit circuit to the antenna elements that transmit the signals. Note that these signals establish an angle of a communication path between the circuit and another circuit.
(FR)L'invention porte sur les modes de réalisation d'un circuit. Dans ce circuit, un circuit d'émission fournit des signaux à des éléments d'antenne durant un mode d'acquisition, un signal donné vers un élément d'antenne donné comprenant au moins deux composantes de fréquence ayant des phases associées, et la phase d'une composante de fréquence donnée dans le signal donné étant différente des phases de la composante de fréquence donnée pour les autres éléments d'antenne. En outre, un nœud de sortie couple le circuit d'émission aux éléments d'antenne qui émettent les signaux. On notera que ces signaux établissent un angle d'un trajet de communication entre le circuit et un autre circuit.
