| Abstract | It is in the nature of communication systems that multiple systems operating in the same spectrum needs to coexist in harmony. This requirement is essential and the MIMO system that we have designed using MB-OFDM also needs to work in an environment in which systems like Wi-Fi, WiMAX, etc. also works. To achieve this, we have focused on use of Active Interference cancellation techniques for MIMO systems to reduce the need for a predetermined interference calculation that is absolute and cannot be changed on short notice or be varied with respect to the prevailing environmental conditions on a real time basis. The choice of MIMO system is to achieve high data rate in short range communication. Moreover, the improvement in the notch depth is still enriched by the proposed method. The main advantage for the improving of notch depth is that it reduces the side lobes there by concentrating the power to the main lobe. This increases the efficiency of the communication network and also reduces the interference. A neural network is a tool that is able to predict an output when it recognizes a given input pattern. In this paper neural network is used to train the system for the desired output and the expected goal is reached. Back propagation algorithm is used to train the system. Cognitive radio is a technique used for efficient spectrum utilization. Spectrum sensing is the gate way for cognition cycle. We have focused on energy detection based spectrum sensing. |

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.
