| Abstract | In February 2002, the FCC (2002 a, b) issued a ruling that UWB could be used for data communications as well as radar and safety applications. UWB system is constrained to have a maximum power transmission of -41 dB and a bandwidth ranging from 3.1-10.6 GHz. UWB co-exists and does not interfere with existing narrowband or wideband communication systems in the same spectrum. However, due to low transmitting power, UWB is affected by the so-called narrowband interference. This paper presents a method to estimate and detect narrowband signals in radio impulse receiver with the intention of eliminating them. The method uses a power spectral density estimation technique called spectrogram to track down the narrowband signal. The spectrogram at specific frequency range of the active narrowband is larger than its overall average power. A threshold detector is built which reports detection at the frequency range where the narrowband is located. The design correctness has been validated by means of Monte-Carlo simulation using UWB IEEE channel models, time hopping-pulse position modulation technique and Rake receiver |

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.
