| Abstract | The problem of the design of eigenstructure estimator banks using a new pseudo-noise approach is addressed. We propose to obtain the underlying estimators for the estimator bank using a new type of resampling of some chosen DOA estimator via pseudo-randomly generated noise. Censored selection of the results of pseudo-randomly resampled estimators is then exploited based on an appropriate local performance test. To illustrate the universality of our pseudo-noise approach and its applicability to the direction finding problem, we formulate a novel pseudo-noise-based estimator bank technique with particular application to the MUSIC estimator, though our concept can be applied in the same way to any other direction finding algorithm as well. The technique presented is shown to have a drastic improvement in the threshold performance relative to conventional MUSIC. The strength of the pseudo-noise approach is demonstrated on simulations and real ultrasonic array data. |

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.
