Two-dimensional interleaving schemes with repetitions

We present 2-dimensional interleaving schemes, with repetition, for correcting 2-dimensional bursts (or clusters) of errors, where a cluster of errors is characterized by its area. Known interleaving schemes are based on arrays of integers with the property that every connected component of area t consists of distinct integers. Namely, they are based on the use of 1-error-correcting codes. We extend this concept by allowing repetitions within the arrays, hence, providing a trade-off between the error-correcting capability of the codes and the degree of the interleaving schemes. © 1997 IEEE.
