Capacity Approaching Run-Length-Limited Codes for Multilevel Recording Systems
Hsin‐Yi Chen, Hong-fu Chou, Mao‐Chao Lin, Shih-Kai Lee · IEEE Transactions on Magnetics · 2010
We propose two constructions for multilevel run-length-limited (RLL) block codes for which the rates are very close to the capacity. For each code construction, we propose a variation that has the advantage of low complexity of encoding and decoding. We conducted a simulation to see the combined effect of channel coding and our proposed RLL coding over an optical recording channel.
