| Description | OFDMA systems inherently take advantages of both frequency diversity gain and frequency-selective scheduling gain. The former is achieved by allocating a user the subcarriers widely scattered over an entire frequency band, while the latter is achieved by allocating a user the subcarriers consecutively located within a subband of a limited bandwidth which is the most favorable to the user among many subbands in the entire frequency band. In this letter, the effect of user mobility is quantitatively investigated in relation to a trade-off between the frequency diversity gain and the frequency-selective scheduling gain in OFDMA systems. As a performance measure, outage capacity is considered. Also studied is how the spatial diversity resulting from multiple antenna techniques and the outage probability affect the dependence of the performance trade-off on the user mobility. |

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.
