| Abstract | Ultra-wideband (UWB) radio is widely perceived as a promising technology for efficient utilization of spectrum and as an enabler of new or improved wireless applications. Besides technological challenges, the potential of causing harmful interference to incumbent narrowband (NB) systems is the major obstacle to successful commercialization of UWB communication systems. It is therefore important to accurately investigate the impact of UWB signals on coexisting NB receivers. In this paper, we describe an analytical approach to study the performance of NB binary phase-shift keying (BPSK) receivers in the presence of multiband orthogonal frequency-division multiplexing (MB-OFDM) UWB interference. MB-OFDM has recently been adopted by the European Computer Manufacturers Association (ECMA) as physical-layer standard for high-rate short-range data communication. Our analysis includes expressions for the exact and asymptotic bit-error rate (BER) a Gaussian approximation (GA) and an impulsive GA (IGA) of the interference signal, and expressions for the amplitude probability distribution (APD) of MB-OFDM interference. We show that GA and IGA may be used for NB signals with, respectively, much smaller and much larger bandwidths than the MB-OFDM subcarrier spacing. For other signal bandwidths and most NB channel models the exact BER analysis has to be used to obtain meaningful results |

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.
