Abstract:
A system for data communication, comprising:a constellation encoder associated with a transmitter, the constellation encoder configured to receive a first and a second series of data bits and encode the data bits into a transmit signal, the transmit signal comprising a plurality of trellis symbols, the plurality of trellis symbols comprising a plurality of transmit symbols; a feedback precoder configured to maintain the magnitude of the transmit signal at a predefined level; a precoder state element configured to monitor a precoder state of the feedback precoder and develop a series of precoder symbols; an interleaver comprising a plurality of registers configured to receive the precoder symbols and store the precoder symbols in the plurality of registers using a first sequence of storage; a trellis state element configured to read the plurality of registers using a second sequence and develop a trellis state output; and a first trellis encoder configured to receive the trellis state output of the trellis state element and configured to generate at least one redundant bit that is a part of the second series of data bits provided to the constellation encoder.
