| Abstract | In this paper, UWB DoA estimation using digital channelization receiver architecture proposed in J.P. Lie, et al is extended to cover the case of multiple UWB emitters employing TH-SS multiple access technique. The principle behind this method is that the spectral analysis of an ideal TH-SS signal consists of a sequence of discrete spectral lines (as derived in M.Z. Win (2002)), which is unique for a certain combination of hopping sequence. Observation on this sequence suggests that it is possible to obtain a unique frequency series of which spectral lines are from the desired signal and no spectral contribution from other signals. An exhaustive search is performed to obtain two hopping sequences that exhibit the same characteristics. Simulation results show that the direction finding function successfully indicates the DoA of the 1/sup st/ signal when the channelizer's frequencies are set for the detection of that signal, likewise for the 2/sup nd/ signal. |

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.
