| Abstract | Impulse Radio Ultra Wide Band (IR-UWB) is the most promising communication technology for low power, short distance, high data rate applications. IR-UWB spectrum being coincided with other narrow band communication systems transmitting high powers is prone to narrow band interference (NBI). In this paper, we have used Gabor Transform to approximate template at receiver with subcarriers. In the present case, we have considered IEEE 802.11a wireless local area network (WLAN) interference at 5.2GHz band. One or more subcarrier(s) centered around 5GHz is/are removed from the template so as to avoid the reception and further processing of the interfering signal. In this paper, we have analytically derived the BER calculation of time hopping pulse position modulation (TH- PPM) UWB system in presence of narrow band interference (NBI) taking into account inter-path interference (IPI), inter-chip interference (ICI) and inter-symbol interference (ISI). The channel model considered is IEEE 802.15.3a channel model. A method for NBI mitigation is proposed and studied for improvement in the BER performance. |

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.
