High-Rate Maximum Runlength Constrained Coding Schemes Using Nibble Replacement

Summary- We will present coding techniques for the character-constrained channel, where information is conveyed using q-bit characters (nibbles), where w prescribed characters are disallowed. Using codes for the characterconstrained channel, we present simple and systematic constructions of high-rate binary maximum runlength constrained codes. The new constructions have the virtue that large look-up tables for encoding and decoding are not required. We will compare the error propagation performance of codes based on the new construction with that of prior art codes. I
