    Abstract: A method of encoding a set of L bits for transmission on a transmission band through a transmission medium is provided, wherein L is a positive integer that is greater than 1. The method includes: mapping, via a mapping component, the L bits into M symbols; dividing, via a first dividing component, the transmission band into sub-bands; allocating, via an allocating component, the M symbols to individual sub-bands, respectively, for transmission at a first time; and allocating, via the allocating component, the M symbols to different individual sub-bands, respectively, for transmission at a second time.

    Abstract: A system includes a DPSK transmitter and a DPSK receiver. The DPSK transmitter is configured to encode a signal and transmit the encoded signal as a sequence of symbols. The DPSK receiver is configured to decode the sequence of symbols into bit values. The DPSK receiver further includes a first decoder which is configured to receive the sequence of the symbols, and to estimate extrinsic information for each symbol and forward the extrinsic information to a second decoder. Moreover, if magnitude of a LLR received form a second decoder is greater than a threshold, the first decoder is configured to determine a bit value of a received symbol, without considering neighboring symbols in the sequence of symbols. Still moreover, if the magnitude of the LLR received from the second decoder is not greater than the threshold, the first decoder is configured to continue to decode the received symbol and consider neighboring symbols in the sequence of symbols.
