ALGORITHMS SUITABLE FOR LOW-COMPLEXITY IMPLEMENTATION OF A CLASS OF RUNLENGTH-LIMITED ERROR CONTROL CODES

Encoding and decoding procedures which exploit the cyclic-like propert ies of a class of runlength-limited error control codes are presented. These algorithms enable simple encoding and decoding circuits consist ing of only a few basic circuit elements to be designed. A comparison with conventional syndrome decoding shows that they provide comparable error performance although requiring considerably less circuitry.
