| Abstract | The wireless ultraviolet (UV) communication technology has received great attention for either short-range high data-rate services or medium-to-large range low-rate sensing applications. However, performance of a UV link is limited by multiple constraints from the current UV laser source and detector technology, and atmospheric link conditions. This paper analyzes performance of both line of sight (LOS) and non-line of sight (NLOS) UV links in terms of signal to noise ratio and bit error rate of the detector. Roles of different parameters, such as data rate, communication range, transmitter power, beam and focal angle, receiving angle and field of view, are studied. Receiving powers for two typical links demonstrate square and linear decaying laws with respect to the communication range respectively. Compared with an LOS link, an NLOS link significantly degrades detection performance from one up to three orders of magnitude for the range from hundreds of meters down to meters. |

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.
