  Interleaved Reed-Solomon codes are applied in numerous data processing, data
transmission, and data storage systems. They are generated by interleaving
several codewords of ordinary Reed-Solomon codes. Usually, these codewords are
decoded independently by classical algebraic decoding methods. However, by
collaborative algebraic decoding approaches, such interleaved schemes allow the
correction of error patterns beyond half the minimum distance, provided that
the errors in the received signal occur in bursts. In this work, collaborative
decoding of interleaved Reed-Solomon codes by multi-sequence shift-register
synthesis is considered and analyzed. Based on the framework of interleaved
Reed-Solomon codes, concatenated code designs are investigated, which are
obtained by interleaving several Reed-Solomon codes, and concatenating them
with an inner block code.
