| Abstract | In this paper we present ULAND® testbed that consists of two European mask compliant impulse radio ultra-wideband (IR-UWB) transceivers with low data rate and medium range for data communication and distance measurement. The transmitter uses Time Hopping spread spectrum codes to reduce the peak to average ratio in the power spectral density and the receiver is based on a filter bank. The hardware/software partitioning of the receiver provides the testbed with the necessary flexibility. Therefore new ranging algorithms can be tested quickly in real time in order to improve the distance measurements. The ranging protocol performs the distance calculation with four-way exchange of the frame even when there is not a common timing reference between transceivers. The algorithms demodulate data and estimate Relative Time of Arrival (RTOA) in a Line of Sight (LOS) and Non-LOS (NLOS) framework. Finally, distance measurement results are presented showing the functionality of the testbed. |

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.
