Abstract:
1. A frame synchronisation method for a multi-band communication system wherein a data signal exchanged between a transmitter and a receiver is organized, by said transmitter, in system frames having a preamble section which contains a frame synchronisation section that includes a number of symbol frames, each of which in turn includes a defined number of slots, whereby each slot corresponds to an individual transmission frequency band, the method comprising: transmitting, by said transmitter, the data signal containing a synchronisation signal in one or more slots of every other symbol frame of the frame synchronisation section; processing, by said receiver, only data signal components selected from transmission frequency bands required for the synchronisation signal transmission; and subtracting, by said receiver, the processed data signal from a shifted copy, whereby the copy is shifted by one symbol frame.
