Abstract

The following is a code that converts unconstrained data strings into (5, 12) run-length limited constrained strings. Its decoder recovers the original data strings, and its error propagation is limited. One error in the encoder string can result in no more than five errors in the decoded data. (Image Omitted) Encoder: Output function depends on an internal state and one data bit. Next-state function depends on an internal state and one data bit. (Image Omitted) Decoder: Output function depends on fifteen constrained bits. (Image Omitted)
