Title (EN) IDENTIFYING A CODE FOR SIGNAL DECODING
(FR) IDENTIFICATION D’UN CODE POUR LE DÉCODAGE DE SIGNAUX
Abstract:
(EN) In some aspects, techniques for wireless signal decoding are described. In some instances, a number of superposition codes are computed based on a set of orthogonal binary codes. The set of orthogonal binary codes includes multiple subsets; each superposition code corresponds to one of the subsets and includes a combination of the binary codes in the corresponding subset. One of the subsets is selected based on a correlation between a wireless signal and the superposition code that corresponds to the subset. One of the binary codes is then selected from the selected subset based on a correlation between the wireless signal and the binary code. The wireless signal is decoded based on the selected binary code.
(FR) Dans certains aspects, la présente invention a trait à des techniques de décodage de signaux sans fil. Dans certains cas, un certain nombre de codes de superposition sont calculés sur la base d’un ensemble de codes binaires orthogonaux. L’ensemble de codes binaires orthogonaux comporte de multiples sous-ensembles ; chaque code de superposition correspond à un des sous-ensembles et comporte une combinaison des codes binaires dans le sous-ensemble correspondant. Un des sous-ensembles est sélectionné sur la base d’une corrélation entre un signal sans fil et le code de superposition qui correspond au sous-ensemble. Un des codes binaires est ensuite sélectionné dans le sous-ensemble sélectionné, sur la base d’une corrélation entre le signal sans fil et le code binaire. Le signal sans fil est décodé sur la base du code binaire sélectionné.
