| Abstract | This paper examines the performance and trade-offs associated with detecting frequency-hop signals by means of multiple observations in the presence of narrowband interfering signals. An adaptive algorithm is proposed for utilizing the outputs from a parallel filter bank observed over a number of time intervals to make decisions on the presence of one or more frequency-hop signals. Trade-offs among the number of filters, the number of time intervals, the time-bandwidth product of each energy detector, and the total observation time are explored by means of computer simulation. The probability of detection for a specified probability of false alarm is determined as a function of the frequency-hop signal power for various numbers of interfering signals. The degradation in performance that results from not observing the frequency-hop signal synchronously with the hops is evaluated, as is the effect of not knowing the hop rate. |

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.
