Mathematical models for super channels with imbedded constrained codes
Hendrik Christoffel Ferreira, C.S. Coetzee, M.A. Herro · IEEE Transactions on Information Theory · 1993
Recursions are developed to determine the error-free runs of error sequences at the output of super channels, which are comprised of some constrained codes employed on renewal inner channels. These error-free runs can be used to obtain the statistical error distribution necessary for evaluating various outer error control codes in concatenated schemes. Experimental evidence that some super channels can be represented with a high degree of numerical precision by partitioned Markov chains is presented.>
