Transmitter and method of transmitting, receiver and method of receiving

A method comprising:

• receiving a signal conveying payload data and signaling data for use in detecting and recovering the payload data, the signaling data and the payload data being arranged in frames in the received signal, the signaling data in each frame being carried by one or more first symbols, each comprised of a plurality of sub-carriers in accordance with a frequency domain sequence, and the payload data being carried by one or more second symbols;
• and
• processing the received signal so as to detect the one or more first symbols and the one or more second symbols, to recover the signaling data from the one or more first symbols, and to use the signaling data to recover the payload data from the one or more second symbols,
• wherein the frequency domain sequence is a sequence associated with a transmitter of the received signal.

A non-transitory computer readable medium including computer program instructions, which when executed by a processor of a receiver cause the receiver to perform a comprising:

• receiving a signal conveying payload data and signaling data for use in detecting and recovering the payload data, the signaling data and the payload data being arranged in frames in the received signal, the signaling data in each frame being carried by one or more first symbols, each comprised of a plurality of sub-carriers in accordance with a frequency domain sequence, and the payload data being carried by one or more second symbols;
• and
• processing the received signal so as to detect the one or more first symbols and the one or more second symbols, to recover the signaling data from the one or more first symbols, and to use the signaling data to recover the payload data from the one or more second symbols,
• wherein the sequence is a sequence associated with a transmitter of the received signal.
