|Abstract||Abstract—This work focuses on the signal to interference plus noise ratio (SINR) comparison of a relaying and a user cooperation strategy. For the relaying strategy we consider operator placed relays in each cell and power control is utilized in the source nodes to achieve a target SINR. For the cooperative strategy, user cooperation with coherent combining is utilized in order to meet a given target SINR at the receiver. Both cases are analyzed in a multi-cell scenario with a soft frequency reuse factor of 3. With 16QAM modulation and no cooperation only 80 % of the users achieve the target SINR. We can show that with user cooperation 82 % of all users achieve the target SINR and with relaying 98%. Index Terms—Relay, user cooperation, cellular networks. I.|

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.
