Abstract
A method for transmitting data between a master modem and at least one slave modem of a master-slave network in orthogonal frequency-division multiplexing, including assigning to each slave modem at least one transmit frequency band and at least one receive frequency band chosen in a range of frequencies likely to be processed by the master modem; and in each slave modem: oversampling, respectively undersampling, each transmitted or received symbol; and filtering upstream of the oversampling, respectively of the undersampling, by a band-pass filter of the corresponding assigned frequency band.
