| Abstract | The measurement method presented in this paper enables the complete characterization of the mobile radio channel including polarization, Doppler behavior, and three-dimensional spatial information (azimuth, elevation, and delay) of the signal multipath components. The method is based on a wideband radio channel sounder and a spherical antenna array. The measurement method enables the separation of multipaths with the same excess delay and Doppler shift as long as their angular separation is not less than 40/spl deg/, and path loss difference not larger than 10 dB. The polarization vector of the signal can also be measured with 9 dB dynamic range. The achieved delay resolution is 33 ns, which corresponds to path length of 10 m. The maximum mobile speed for /spl plusmn/2% phase accuracy is 10 m/s. The measured channel statistics can be used for evaluation of antennas for mobile handsets, as well as developing polarization and radiation pattern diversity antennas for handsets. |

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.
