A frame synchronisation is proposed for a multi-band communication system, wherein a data signal exchanged between a transmitter and a receiver is organised in system frames having a preamble section which contains a frame synchronisation 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 synchronisation signal in one or more slots of every other symbol frame of the frame synchronisation section, processing only data signal components selected from transmission frequency bands required for the synchronisation signal transmission, and subtracting the processed data signal from its shifted copy, whereby the copy is shifted by one symbol frame.
Frame synchronisation method for a multi-band communication system wherein a data signal exchanged between a transmitter and a receiver is organised in system frames having a preamble section which contains a frame synchronisation 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 comprising steps for
Transmitter for a frame based multi-band communication system, wherein a data signal to be transmitted is organised in system frames having a preamble section which contains a frame synchronisation 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 transmitter comprising a preamble control means for controlling the content of the preamble section such, that a synchronisation signal is modulated onto every other symbol frame of the frame synchronisation section.
Receiver for a frame based multi-band communication system, wherein a received data signal is organised in system frames having a preamble section which contains a frame synchronisation 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 receiver comprising:
