Patent ID: 8824571

Claim:
A method of transmitting and recovering data traversing a telecommunication channel, the method comprising: forming a first frame of a plurality of frames using a frame module, the first frame comprising a first control codeword including information relating to a first format used for a first data payload included in the first frame, the first control codeword selected from a non-linear block code and having a first distance spectrum that is sufficient to be decodable by a receiver at a minimum signal to noise ratio at which the first data payload is also decodable by the receiver; forming a second frame of the plurality of frames using the frame module, the second frame having a same frame duration as the first frame and comprising a second control codeword including information relating to a second format used for a second data payload included in the second frame, the second control codeword selected from the non-linear block code and having a second distance spectrum that is sufficient to be decodable by the receiver at a minimum signal to noise ratio at which the second data payload is also decodable by the receiver, and wherein the second distance spectrum is different from the first distance spectrum and the first control codeword is at least as strong as the first data payload and is weaker than the second data payload and the second control codeword is at least as strong as the second data payload; and transmitting the plurality of frames into a telecommunication channel using a frame transmission module.
