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