Abstract | A new design to provide unequal error protection (UEP) using Raptor codes over erasure channels, named Intermediate Symbols Expanding Window Raptor (ISEW Raptor) codes using windowing techniques, is developed and discussed. ISEW Raptor encodes intermediate symbols with EWF approach, possessing UEP property while keeping systematic code characteristics. ISEW Raptor is improved based on standard Raptor (adopted by the third generation partnership project, namely 3GPP), and of which the core codec algorithms are also compatible with standard Raptor. ISEW Raptor introduces an additional parameter in the UEP code design, making it more general and flexible in application. Furthermore, the proposed approach shows excellent UEP performance that MIB could be decoded successfully with high probabilities even for less than number of source symbols received, and which is confirmed experimentally. |

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.
