Abstract
A transmitter is provided for transmitting data to a communication channel and a receiver receives the data from the communication channel. The transmitter comprises an encoder to encode data and a linear block encoder to encode data encoded by the encoder. The receiver comprises a soft channel decoder to decode the data, and a soft linear block code decoder to decode data decoded by the soft channel decoder. In the first iteration, the soft channel decoder decodes data received by the receiver. In succeeding iterations, the soft channel decoder decodes the data received by the receiver and utilizes information from the soft linear block decoder from an immediate preceding iteration. A decision circuit selects an output of the soft linear block decoder if an evaluated criterion is less than a threshold, or an output of the soft channel decoder if the evaluated criterion is greater than the threshold. A decoder decodes an output of the threshold check circuit.
