WebbThe listsize capacity is computed for the Gaussian channel with a helper that—cognizant of the channel-noise sequence but not of the transmitted message—provides the decoder with a rate-limited description of said sequence. This capacity is shown to equal the sum of the cutoff rate of the Gaussian channel without help and the rate of help. WebbA soft-decision channel-capacity for different fiber-optics communications channel-models is discussed. Short low-density parity-check codes of very-high code-rates, large minimum distance, low-complexity encoding and decoding approaching the Shannon's limit within 0.7 dB at BER of 5×10-7 are presented, 2.5 dB better than turbo codes.
