| Abstract | Runlength-limited (RLL) codes, also known as (d,k) RLL codes, are used in digital magnetic recording and have potential use in soliton optical communication. We show how our approach to RLL coding can naturally incorporate multilevel error correction coding. It allows us not only to correct shift errors but also insertions and deletions of zeros. The main method for achieving this is to use Lee-metric codes. The component codes of the multilevel block code are chosen such that this code has a large minimum Lee distance and such that the (d,k) RLL code combined with the error correction multilevel code provides the highest possible rate. We emphasize that multilevel (d,k) RLL coding combined with multilevel block coding for error correction is well suited to multistage decoding. We also show that for an appropriate choice of the normalised thresholds of these parallel codes, the rate of the corresponding (d,k) RLL code converges to the capacity of the (d,k) constraint, as the dimension of each of the parallel codes goes to infinity. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
