| Abstract | An adaptive joint frame synchronization and carrier frequency offset estimation scheme in orthogonal frequency division multiplexing (OFDM) systems is proposed in this paper. Compared with conventional algorithm, the proposed one can reduce the Cramer-Rao lower bound (CRLB) to the minimum without changing the total energy consumption. In the proposed scheme, a variable parameter M is introduced in generating training sequence, where M is a function of the maximum multipath delay of the multipath channel. By adaptively adjusting M, the optimum training sequence can be obtained. Accurate frame synchronization and carrier frequency offset acquisition can be performed simultaneously in the proposed scheme. An adaptive tracking algorithm in the proposed scheme is also needed to estimate the remaining carrier frequency offset after acquisition. By using the proposed optimum training sequence, considerable performance improvement in the proposed tracking algorithm over Moose algorithm can be obtained. |

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.
