A General Fixed Rate Arithmetic Coding Method for Constrained Channels

by S. J. P. Todd, G. G. Langdon,Jr., G. N. N. Martin
This paper extends the result of earlier work on the application of arithmetic codes to the constrained channel problem. We specifically present a general length-based fixed rate implementation technique which performs the arithmetic coding recursions during each channel time unit. This technique is superior to an earlier unpublished code for general constrained channels. The approach permits the design of codes for sophisticated channel constraints.
