An SCCC decoding system is provided. The system is comprised of an outer decoder module (208), permutation module (104), and data store (114). The outer decoder module is configured to generate a first sequence of soft-decision bits x[n] for n=0, 1, 2, . . . , N-1. The permutation module is configured to permute the first sequence of soft-decision bits x[n] to generate a second sequence of soft-decision bits y[n]. The first sequence of soft-decision bits x[n] is generated by the outer decoder module in accordance with a mapping v[n]. The second sequence of soft-decision bits y[n] is generated for communication to an inner decoder module (204). The data store contains a mapping v[n]. The mapping v[n] satisfies a mathematical equation v[k+m.(N/M)] modulo (N/M)=v[k] modulo (N/M) for m=0, . . . , M-1 and k=0, . . . , (N/M-1), (N/M) is an integer.
