| Abstract | Let the parameter vector of a baseband pulse be ¿=[D, A, W]T, where D=arrival time, A=amplitude, and W=width. A method for estimating ¿ for a pulse present in a noisy data segment is given. We start by performing an autoconvolution (AC) of the data segment, and then recording the shift where the AC peaks. By taking half of that shift, from the end of the segment, a point is placed near the middle of the pulse. Next, we partition the pulse at that point and perform two more ACs, (one on the left half of the pulse and another on the right half), and find two more shifts where the ACs peak. These two shifts provide coarse measurements on D and W. A further refinement by least squares (LS) then produces a final estimate for ¿. Simulation results have corroborated the theoretical development and shown that the new estimator performs close to the Cramer-Rao lower bound (CRLB). |

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.
