Abstract
A method for trellis constellation shaping is disclosed. In one embodiment, this method comprises receiving two or more input bits and filtering at least one of the two or more input bits to create two or more filtered output bits. The step of filtering at least one input bit introduces at least one extra bit. The method then encodes the input bits which are not filtered to create encoded bits and stores the encoded bits and the filtered bits in a buffer. A processing element may be configured to perform Viterbi type processing on the filtered bits to create processed bits. The method combines at least one of the processed bits with at least one of the buffered bits to create a combined bit set from the buffered bits and then performs mapping on the combined bet set to thereby map the combined bit set into a constellation.
