The authors introduce a new simple encoding technique which allows the design of a wide variety of linear block codes. They present a number of examples in which the most widely used codes (Reed-Muller, Hamming, Golay, optimum etc.) have been designed. They also introduce a novel trellis design procedure for the proposed codes. It is shown that the trellises of the designed codes are similar to the trellises of coset codes and allow low complexity soft maximum likelihood decoding.
