| Abstract | Vehicle to vehicle (V2V) communication has gained renewed interest among research community which is further signified by the allocation of dedicated spectrum and an IEEE standard for their usage in recent years. However, 802.11p, the current IEEE standard for vehicular communications, has a relatively low multiplicity (the number of links that it can simultaneously support). In this work, we propose a new vehicular communication scheme based on sectored antennas in order to improve the multiplicity performance. We first show that a sectored antenna based vehicular communication system has higher multiplicity than 802.11p. To further enable multiple transmit sectors to communicate with a receive node simultaneously in a single receive sector, using an OFDMA system design, we propose a new sector-specific pilot design and corresponding channel estimation over time and frequency domains of the channels corresponding to various sectors. Finally, the performance characteristics of the proposed scheme are shown through simulations. |

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.
