Title (EN) RFID READERS AND TAGS TRANSMITTING AND RECEIVING WAVEFORM SEGMENT WITH ENDING-TRIGGERING TRANSITION
(FR) LECTEURS ET ETIQUETTES RFID A TRANSMISSION ET RECEPTION DE SEGMENT DE FORME D'ONDE COMPORTANT UNE TRANSITION DE FIN-DECLENCHEMENT
Abstract: front page image
(EN)RFID readers exchange information with RFID tags. The information is encoded for transmission and decoded upon reception. Encoding is in binary bits, which are in turn encoded in waveform segments. The last transmitted waveform incorporates an ending-triggering transition, and terminates in a preset manner with respect to when the ending-triggering transition occurs. Parsing while decoding can happen by waiting for the ending-triggering transition, and then waiting according to the present manner. This way there is no ambiguity in the ending of the waveform, and no End Frame is necessary.
(FR)On décrit l'échange d'information entre lecteurs et étiquettes RFID. L'information est codée pour la transmission et décodée à la réception. Le codage s'effectue en bits binaires, à leur tour codés en segments de forme d'onde. La dernière forme d'onde transmise incorpore une transition de fin-déclenchement, et se termine selon un mode préétabli par rapport à l'occurrence de la transition. On peut effectuer l'analyse syntaxique durant le décodage en attendant ladite transition, puis intervient l'attente selon le mode préétabli. Cela lève toute ambiguïté quant à la fin de la forme d'onde, et on peut donc se passer de trame de fin (End Frame).
