A Scheme for Combined Modulation and Error Correction
Khaled Abdel-Ghaffar, Mario Blaum, Jos H. Weber · 2005
A technique for joint modulation and error correction is described. In order to construct a (d, k) modulation code with k information bytes that corrects up to t errors, a single error-detecting (inner) block modulation code is combined with an (outer) [k + t, k] Reed-Solomon code. The performance of this scheme is compared to the related scheme using an (inner) block modulation code and an (outer) [k + 2t, k] Reed-Solomon code, as well as to the traditional method in magnetic recording, which involves the concatenation of an error-correcting code with a sliding window modulation code.
