Interleaving of Reed-Solomon Viterbi Concatenated Coding Channel

Abstract

In this paper, two interleaving schemes are discussed and several R-S code array synchronization configurations are investigated. A procedure for obtaining synchronization sequences, for the R-S code array, under specified conditions is suggested and it is followed by the identification of sequences with desirable properties. Several graphs are presented, e.g., false synchronization probability versus various bit error rates for the number of errors permitted, and also, the missed synchronization probability versus various bit error rates for number of errors permitted and for various lengths of synchronization sequences. For the interleaving schemes discussed there is no analytical advantage, with respect to array synchronization, for selecting one scheme over the other.
