Abstract

Previously proposed trellis decoding of array codes cannot be applied to simple product codes having any number of rows and columns. A modified scheme is proposed that can be used with all square and rectangular codes. It is illustrated by simulation study, that using soft decision trellis decoding we can correct a number of errors approaching 3 dmin and that even hard decision trellis decoding corrects errors in excess of dmin. The performance curves of a wide range of product codes are presented and compared
