Abstract :
A systematic procedure is presented for modifying standard binary error control codes (ECCs) to form runlength-limited ECCs without reducing rates or affecting minimum distances. This procedure is then optimised to find the tightest runlength bound given an EEC defined by its generator matrix. A simple example based on the BCH (15,5) ECC is presented to illustrate the procedure, which is nonetheless more generally applicable. The effects of the modification on spectral characteristics are also considered.<>
