A high-rate constrained code is provided to encode/decode channel data. A transformer translates binary channel data into an arbitrary alphabet size. The transformer selects an indicator word and makes forbidden prefix substitutions in the data to be transformed. A finite-state encoder imposes some user-defined constraint on the transformed data before the data is transferred to the channel. The high-rate constrained coding technique may be used to produce high-rate DC-limited and run-length-limited codes. The high-rate code can be used in tandem with error-correcting codes.
