| Abstract | Systems coexistence is becoming a very challenging issue. Due to the imperfections of the RF (radio frequency) front-end filters, the out-of-band spurious emission from the transmitter is occurred, as well as the receiver selectivity inaccuracy. Those two factors cause different interference levels depending on the transmitted power, the duplex mode of the technology, and also on the distance between terminals. We present in this paper an evaluation to the interference caused by the inter-system coexistence using a mathematical model for both the out-of-band spurious emission, and the receiver selectivity. This framework is then used to estimate the inter-system interference impact on the WiMAX CPEs (customer premises equipment), and hence on the performance of a WiMAX network in terms of capacity. Monte-Carlo approach has been used to estimate the WiMAX network capacity using a simple system level simulator. Different simulation scenarios are considered, all in the DL (downlink) direction. Coexistence with other systems such as Bluetooth is perceived to impact the WiMAX network. The users' applications have also revealed their impact on the capacity. |

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.
