Title (EN) CYCLIC SHIFT DIVERSITY FOR RANGE ESTIMATION IN WIRELESS NETWORKS
(FR) DIVERSITÉ DE DÉCALAGE CYCLIQUE POUR ESTIMATION DE DISTANCE DANS DES RÉSEAUX SANS FIL
Abstract:
(EN) A wireless communication device, system, and method. The device includes a memory, and processing circuitry coupled to the memory, the memory including logic. The processing circuitry is to implement the logic to: process a first packet from another device; encode a second packet to the other device by applying cyclic shift delay (CSD) to symbols of the second packet, the CSD being based on a time of arrival (ToA) of the first packet at the device; cause transmission of the second packet such that a time interval between a Fast Fourier Transform (FFT) clock boundary of the first packet and a FFT clock boundary of the second packet at the device is a predetermined integer number of clock cycles of a sampling clock of the device.
(FR) L'invention concerne un dispositif, un système et un procédé de communication sans fil. Le dispositif comprend une mémoire et une circuiterie de traitement couplée à la mémoire, la mémoire comprenant une logique. La circuiterie de traitement doit mettre en œuvre la logique pour : traiter un premier paquet à partir d'un autre dispositif ; coder un second paquet au niveau de l'autre dispositif par l'application d'un retard de décalage cyclique (CSD) à des symboles du second paquet, le CSD étant basé sur un temps d'arrivée (ToA) du premier paquet au niveau du dispositif ; provoquer la transmission du second paquet de telle sorte qu'un intervalle de temps entre une limite d'horloge de transformée de Fourier rapide (FFT) du premier paquet et une limite d'horloge FFT du second paquet au niveau du dispositif est un nombre entier prédéterminé de cycles d'horloge d'une horloge d'échantillonnage du dispositif.
