| Abstract | 3GPP Long Term Evolution (LTE) is the next generation network technology for beyond 3G. In the LTE system deployment, there may not be much separation between the frequency bands assigned to operators. Therefore, adjacent channel interference analysis between two coexisting LTE systems is a potentially important research field. In this paper, we investigate the coexistence problem between a macrocell and small cells, i.e., microcells and picocells, in LTE networks. We focus on analyzing the adjacent channel interference (ACI) between two coexisting systems with different duplex modes, i.e., frequency division multiplexing and time division multiplexing, deployed in adjacent frequency bands. Main contribution of this paper is to present the coexistence results of two systems by evaluating the macrocell performance degradation caused by ACI when it operates with microcell/picocell on adjacent channel in some typical interference scenarios. Based on comparison and analysis of simulation results, we find that in some scenarios two LTE systems could not coexist well under current LTE radio frequency requirements. We also present some suggestions and mitigation technologies to avoid large throughput loss due to ACI. |

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.
