| Abstract | In this paper, we investigate the outage behavior of a dual-hop $N^{th}-best$ decode-and-forward (DF) relay system with co-channel interference (CCI) at both the relays and the destination. The source-relay and relay-destination channels as well as the interferers' channels at both the relay and the destination nodes are assumed to follow Rayleigh distribution. Exact closed-form expressions for the outage probability for both independent non-identically distributed (i.n.d.) and independent identically distributed (i.i.d.) cases of interferers' channels are derived in this paper. Furthermore, the system behavior at high signal-to-noise ratio (SNR) values is studied via deriving an approximate expression for the asymptotic outage probability as well as the diversity order and the coding gain. The analytical results are supported and validated by Monte-Carlo simulations. Our findings suggest that the diversity order linearly increases with the number of relays and linearly decreases with the order of the relay. Also, the results show that the system is still able to achieve full diversity gain in the presence of finite number of interferers with finite powers. |

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.
