| Abstract | A user-centric wireless cellular network has recently emerged as a pragmatic network model for better reflecting the traffic demand-based deployment. To the best of authors' knowledge, however, the coverage probability with composite κ – μ shadowed and lognormal shadowed fading [termed the doubly-selective (DS) fading] in downlink user-centric wireless cellular networks is unknown. Most importantly, another significant performance metric, i.e. the average rate, until now has not been investigated. To study the influence of the DS fading on performance metrics and avoid unnecessary handovers caused by the random fluctuation of the lognormal shadowing at the cell-association phase, this work considers the downlink user-centric wireless cellular network with the DS fading and the closest cell-association rule. Furthermore, the closed-form expressions for the coverage probability and average rate in downlink user-centric wireless cellular networks are successfully derived. Numerical results demonstrate that the user-centric wireless cellular network not only provides a high coverage probability but also promotes the average rate compared to the Poisson point process-based network with independent uniformly distributed users. |

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.
