| Abstract | This study presents the performance analysis of multiple-antenna two-way amplify-and-forward relay network in an interference-limited environment. To avoid the high feedback overhead and to fully exploit a multiple-antenna diversity, the authors employ transmit and receive antenna selection at the user node and analog network coding at the relaying node. Specifically, they formulate the exact expressions of the generalised signal-to-interference-plus-noise ratio (SINR). On the basis of the derived SINR, the upper-bounded cumulative distribution function is obtained. Subsequently, the outage probability (OP) and symbol error rate (SER) are determined and investigated. To assess the overall performance of the system, they present approximate but simple expressions for the overall OP (OOP) and overall SER. To gain insights, asymptotic expressions of OP and OOP are provided, which enable the characterisation of the achievable coding gain and diversity order of the system. Besides, they derive upper bounds on the achievable rate based on Jensen's inequality. Furthermore, they formulate three optimisation problems to minimise outage, namely optimal relay location under fixed power allocation, optimal power allocation under fixed relay location, and joint ORL and power allocation. Finally, the tightness of their analysis is attested through Monte Carlo simulation. |

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.
