A system, method and computer-readable medium for encoding and decoding digital information over a channel is provided. Type Mapping is employed and is based on the partitioning of vectors over an alphabet into “types” and using enumeration for the encoding and decoding process. Type mapping allows for signal alphabets of arbitrary size and date rate flexible coding. Tradeoffs between optimal rate versus Signal to Noise Ratio are provided and works as a compliment to the Forward Error Control that may be employed in communications products.
