Carrier recovery system and method

A processing module for a receiver device, the processing module configured to:

• receive a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion, and a data-payload-portion;
• and
• perform a carrier recovery process on the signal, wherein at least part of the security-sequence-portion of the one or more frames is excluded from the carrier recovery process.

A system comprising:

• at least one receiver device comprising the processing module according to any preceding claim;
• and
• at least one transmitter device comprising a transmitter processing module configured to communicate with the at least one receiver device, the transmitter processing module configured to generate a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion, and a data-payload-portion.

A method for operating a processing module of a receiver device, comprising:

• receiving a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion, and a data-payload-portion;
• and
• processing the signal to perform carrier recovery, and excluding at least part of the security-sequence-portions of the one or more frames from the carrier recovery process.
