Title
(EN) A METHOD OF PACKET FORMAT DEPENDENT SELECTION OF MIMO-OFDM DEMODULATOR
(FR) PROCÉDÉ DE SÉLECTION D'UN DÉMODULATEUR MROF-MIMO EN FONCTION DU FORMAT DES PAQUETS
Abstract
(EN)
Systems and methodologies are described that facilitate code rate and modulation order dependent selection of a suitable demodulator for a received data packet. According to various aspects, systems atid/or methods are described that enable selection of an optimal demodulation scheme such that signal receiver complexity is not increased and optimal decoding throughput performance is achieved.
(FR)
La présente invention concerne des systèmes et des méthodologies qui permettent de sélectionner, en fonction du débit de code et de l'ordre de modulation, un démodulateur approprié à un paquet de données reçu. Selon divers aspects, on décrit des systèmes et/ou des procédés qui permettent de sélectionner un plan de démodulation optimal de sorte que la complexité du récepteur de signal ne soit pas augmentée et qu'un résultat de vitesse de décodage optimale soit atteint.
