| Abstract | Error estimating coding (EEC) has recently been established as an important tool to estimate bit error rates in the transmission of packets over wireless links, with a number of potential applications in wireless networks. In this paper, we present an in-depth study of error estimating codes through the lens of Fisher information analysis and find that the original EEC estimator fails to exploit the information contained in its code to the fullest extent. Motivated by this discovery, we design a new estimator for the original EEC algorithm, which significantly improves the estimation accuracy, and is empirically very close to the Cramer-Rao bound. Following this path, we generalize the EEC algorithm to a new family of algorithms called gEEC generalized EEC. These algorithms can be tuned to hold 25-35% more information with the same overhead, and hence deliver even better estimation accuracy---close to optimal, as evidenced by the Cramer-Rao bound. Our theoretical analysis and assertions are supported by extensive experimental evaluation. |

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.
