| Abstract | A novel synchronization algorithm based on training sequence is proposed for OFDM systems. Different from the existed algorithms with a symmetric training sequence, it uses the training sequence consisting of one CAZAC sequences with the same length and nonsymmetrical structure. The proposed method firstly uses the property of good self-correlation and constant amplitude of the CAZAC sequence to get the coarse timing and fractional frequency offset, and then uses the relation between the deviation of the coarse timing and the frequency offset for the fine timing and frequency offset estimation. Computer simulation results show that the performance of the proposed algorithm is much better than the existing ones in terms of timing and frequency accuracy, and that the frequency offset estimation range is up to the whole channel band. Moreover, when the SNR is high, the MSE of the frequency offset estimation approaches to the Cramer-Rao Bound. |

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.
