摘要
A method of line coding is disclosed that limits error propagation in a decision feedback equalizer (DFE) of a receiving device. A communications device receives a set of bits to be transmitted over a channel and divides the set of bits into a plurality of blocks based, at least in part, on a line coding scheme. The device then encodes each of the blocks of bits into a corresponding block of symbols based on the line coding scheme. Specifically, the line coding scheme has a non-uniform coding efficiency, wherein a first bit or a last bit of each block of bits is mapped to a single data symbol. For some embodiments, the line coding scheme may be a ternary line coding scheme that maps a block of 3k+1 bits to a corresponding block of 2k+1 symbols, where k is an integer greater than 1.
