Abstract
In data communications, a suitably designed contrast coding scheme, comprising a process of contrast encoding () at a transmitter end () and a process of contrast decoding () at a receiver end (), may be used to create contrast between the bit error rates 'BERs' experienced by different classes of bits. Contrast coding may be used to tune the BERs experienced by different subsets of bits, relative to each other, to better match a plurality of forward error correction 'FEC' schemes () used for transmission of information bits (), which may ultimately provide a communications system () having a higher noise tolerance, or greater data capacity, or smaller size, or lower heat.
