| Abstract | This paper considers the application of opportunistic multiuser multiple-input multiple-output (MU-MIMO) techniques to multicarrier wireless networks based on orthogonal frequency division multiplexing (OFDM). Unlike related work where the design of the MU-MIMO component is jointly performed with the subcarrier allocation among the users (e.g. some form of OFDMA is present), here it is assumed that the selected users will have to share the utilization of all the subcarriers in the system. This scenario would be typical of deployments based on time multiplexing policies (e.g., WLANs) where the proposed MU-MIMO add-on would serve to increase the system capacity. A new algorithm is introduced to select the users taking into account their channel response over all subcarriers and performing a joint frequency-space power allocation. Numerical results demonstrate very significant improvements in terms of sum-rate capacity in comparison to a conventional (opportunistic) TDMA scheme. |

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.
