System and method for adaptive low-density parity-check (LDPC) coding

An apparatus comprising:

• a first means for processing data during a connection between the apparatus and another apparatus, the data being processed in accordance with a predetermined coding scheme;
• a second means for selecting or receiving a selection of feedback code information during the connection, the feedback code information comprising information from which a parity-check matrix is constructable, the feedback code information comprising one of a seed parity-check matrix, an exponent matrix, an index of a parity-check-matrix-related permutation matrix, or an index of an exponent-matrix-related permutation matrix;
• and
• a third means for switching the processing step to process data during at least a portion of the connection in accordance with a parity-check coding technique based upon the feedback code information.

A method comprising:

• processing data during a connection between an apparatus and another apparatus, the data being processed in accordance with a predetermined coding scheme;
• selecting or receiving a selection of feedback code information during the connection, the feedback code information comprising information from which a parity-check matrix is constructable, the feedback code information comprising one of a seed parity-check matrix, an exponent matrix, an index of a parity-check-matrix-related permutation matrix, or an index of an exponent-matrix-related permutation matrix;
• and
• switching the processing data to processing data during at least a portion of the connection in accordance with a parity-check coding technique based upon the feedback code information,
• wherein processing data and switching the processing are performed by a processor configured to process the data and switch the processing.
