| Abstract | The Space and Terrestrial Communications Directorate of the U.S. Army's Communications- Electronics Research, Development and Engineering Center is executing a proof of concept program to develop and demonstrate an AllDigital Satellite Communications Earth Terminal. The Future Advanced Satellite Terminal (FAST) program initially focuses on the satellite terminal's receive component of the satellite link. The two main efforts under FAST are a multi-carrier wideband digital downconverter and a wideband multi-carrier advanced signal processor. The downconverter is designed to simultaneously capture at L-band Intermediate Frequency (IF) all of the signals in a selectable 125 MHz-wide transponder bandwidth of the Wideband Global SATCOM (WGS) satellite and convert them into a digital in-phase and quadrature signal. This digitized signal is then passed over an American National Standards Institute (ANSI) VMEBUS International Trade Association (VITA) 49 interface to the wideband multi-carrier advanced signal processor, which will simultaneously process at least eight communications signals. Future plans for a complete transmit and receive terminal capability and a potential migration path from fixed frequency division multiple access (FDMA) carriers to a more dynamic process for allocating bandwidth, decentralized power monitoring and control, and remote terminal control are also discussed. |

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.
