| Abstract | The overall performance of ultra-wideband (UWB) communication systems relies critically on the energy capture capability of UWB receivers. A family of transmitted-reference (TR) UWB receivers has been proposed to achieve effective energy capture at the cost of enhanced noise effect and reduced system capacity. In this paper, we investigate a new receiver structure based on a noisy template (NT). The NT-based receiver enjoys effective signal energy capture and low complexity as the TR family. It has better system capacity and less noise effect with respect to TR UWB. To shed light on the quantitative noise effect of our NT receiver, we derive closed-form expressions for the bit error rate (BER) performance in both sparse and dense multipath channels. Through analysis; we demonstrate that the NT reception scheme effectively alleviates the noise effect as the number of pilot symbols increases, without sacrificing the data rate. We also illustrate the relationship between the channel diversity gain and its ability in compensating for the noise effect. |

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.
