| Abstract | This paper investigates the issue of minimizing the detection time while guaranteeing the desired detection accuracy in cooperative primary user detection for cognitive radio. To achieve this goal, the sequential cooperative energy detection (SCED) scheme is firstly introduced. This scheme implements sequential probability ratio test to make final decisions and can guarantee the desired detection accuracy with less detection time compared with other schemes. Then, detection time in the SCED scheme is minimized by choosing an optimum sample number. Expressions for the optimum sample number and the minimum detection time in four typical scenarios are also derived. Simulation results are presented to illustrate the benefits of the SCED scheme and to examine the optimum sample number as well as the minimum detection time. |

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.
