| Abstract | One of the drawbacks of orthogonal frequency division multiplexing (OFDM) systems is the large out-of-band (OOB) emissions. These emissions are undesirable and may cause harmful interference to adjacent channels (users). Reducing the OOB emissions may allow more users to access the spectrum especially in the case of dynamic spectrum access networks. In this paper, we investigate the ability of combining two practical OOB emissions reduction techniques. The combination is proposed to mitigate the drawbacks of each individual technique while providing significant OOB emissions reduction. The chosen techniques do not require performing complex optimizations which makes the combination suitable for practical implementations. The effectiveness of the proposed combination is verified via computer-based simulations as well as practical implementation. The implementation is done using Iris software defined radio along with the universal software radio peripheral (USRP-N210). Implementation results prove that this combination can be used in real-time applications. |

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.
