Claim 6:
7. A node device called “first node device” in a power line communication network, the first node device being configured so as to communicate in one or more separate frequency bands with a second node device (134) of said network, the first node device is furthermore configured so as to apply a reception mode for receiving data in one or more of said one or more separate frequency bands in parallel, and in that the first node device comprises electronic circuits configured so as to:
convert the data received 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,
filter said first series of data in parallel through the same number of filtering circuits as there are frequency bands for which the first node device is configured in reception mode, 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,
demodulate 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,
record the third series of data in a first buffer memory, and
de-interleave data from said first buffer memory to get de-interleaved data, for each of the separate frequency bands, in a de-interleaving mode specific to one of the one or more separate frequency bands for which the de-interleaving is performed and, if the de-interleaved data are coherent, supply the de-interleaved data with a view to subsequent processing.
