Claim 0:
1. A transmission method in a first node device of a power line communication network, the first node device being configured so as to apply a reception mode for receiving data transmitted by a second node device in one or more separate frequency bands in parallel, the method comprises steps of:
converting the received data in the form of an analogue signal in one or more of said one or more separate frequency bands into a first series of data,
filtering said first series of data in parallel through the same number of filtering circuits as the number of frequency bands in the one or more separate frequency bands, so as to obtain the same number of second series of data as there are frequency bands for which the first node device is configured in reception mode,
demodulating said second series of data through the same number of demodulation circuits as there are frequency bands for which the first node device is configured in reception mode, so as to obtain third series of data,
recording the third series of data in a first buffer memory, and
de-interleaving data from said first buffer memory to get de-interleaved data, for each of the one or more separate frequency bands, in a de-interleaving mode specific to one of the one or more the separate frequency bands for which the de-interleaving is performed, detecting whether the de-interleaved data are coherent and, if the de-interleaved data are coherent, supplying the de-interleaved data with a view to subsequent processing.
