ABSTRACT:
A data transmission system is provided for transmitting user data to and receiving data from a communication channel, comprising a first address generator to generate a first address in accordance with the user data. A linear block encoder encodes the user data in response to the first address from the first generator. A transmitter transmits an output of the linear block encoder to the communication channel, and a soft channel decoder to decode data. A second address generator generates a second address in accordance with the decoded data from the soft channel decoder, and a soft linear block code decoder decodes data decoded by the soft channel decoder in accordance with the second address from the second address generator.
