| Abstract | An experimental system for public demonstration of speech and data transmission in a digital mobile environment is described. The speech link incorporates multipulse coding at 10 kb/s and Reed-Solomon channel coding of 3 kb/s for a total of 13 kb/s per channel. The data codec uses a packet assembler/disassembler to convert from a radio data-link-layer protocol to a 9.6-kb/s asynchronous communication protocol. The data stream is protected by a (56,39) Reed-Solomon code and by the automatic repeat request of the data-link-layer protocol. Speech and data are carried on independent 16-kb/s streams multiplexed into a 48-kb/s TDMA channel. Subjective and objective performance results reported for a variety of transmission experiments verify that good-quality speech transmission and high-throughput data transmission with excellent integrity are achievable over a channel characterized by a 14-dB carrier-to-interference ratio.< |

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.
