Abstract  Abstract

A method of digital data transmission between a first transceiver and a second transceiver is disclosed. The first transceiver has a first transmitter and a first receiver and the second transceiver has a second transmitter and a second receiver. The first transmitter also contains a programmable encoder for encoding its transmission, while the second receiver uses at least one of a plurality of error correcting codes (ECCs) for decoding its reception. Each ECC can be specified by a predetermined set of parameters. The method comprises the steps of: establishing connection between the first and second transceivers; the second receiver selecting which one of the plurality of ECCs for transmission by the first transmitter, each of the plurality of ECCs capable of being represented by at least one method of implementation described by a sequence of state transitions; the second receiver generating a corresponding set of parameters based on the ECC selected; the second receiver communicating the parameters to the first transmitter; the first transmitter inserting the parameters in its programmable encoder to generate the ECC to encode the digital data for transmission; the first transmitter transmitting the encoded digital data to the second receiver, and the receiver decoding the encoded digital data based on the ECC.
