Abstract | In this study, the electromagnetic interference of an MB-OFDM UWB system with an IEEE802.11a wireless LAN was evaluated using a GTEM cell. Band #3 (out-of-band radiation for 11a) in the band plan of the MB-OFDM UWB system and Band #4 (in-band radiation for 11a) were assumed to be two different types of interference. As a result, when the frequencies of the MB-OFDM UWB corresponded to Band #3, the MB-OFDM UWB system may not interfere with the wireless LAN. In the other band, although the interference power of the MB-OFDM UWB was less than the receiver noise of the wireless LAN, the MB-OFDM UWB system interfered with the wireless LAN. In addition, the separation distance was evaluated from the power inputted to the GTEM cell. As a result, for the vicinity of the minimum receiver sensitivity of the wireless LAN, the separation distance was about 3 m. Finally, the amplitude probability distribution (APD) of the MB-OFDM UWB system that was the interference source was evaluated. As a result, the APD characteristics of MB-OFDM UWB were slightly different from those of additive white Gaussian noise (AWGN). |

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.
