| Abstract | In most time-based ultra-wide bandwidth (UWB) localization systems, ranging is usually accomplished by the time-of-arrival (TOA) estimation of the first path, which is more challenging in dense multipath channels. This paper proposes a novel time reversal (TR) based method for TOA estimation in UWB ranging. It uses a time reversed version of channel impulse response (CIR) to compensate for the highly cluttered environments. After the time reversed waveform is retransmitted into the same channel, the performance of TOA estimation will be significantly improved by simply search the maximum peak in the output of the receiver. The advantages of TR based method are verified by simulations using the classical IEEE 802.15.4a channel models. Results show that the bias and root mean square error (RMSE) of TR based method are greatly reduced compared to the usually used maximum likelihood method. |

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.
