| Abstract | The next generation wireless LAN standard IEEE 802.1 In adopts MIMO-OFDM (multi-input multi-output orthogonal frequency division multiplexing) as a key technology in physical layer. In this paper, the effect of sampling clock offset is analyzed, an algorithm of sampling clock offset estimation is proposed on the system in presence of sampling clock offset. The algorithm is based on the long training field of the preamble, utilizing the correlation between the two same long training symbols. It can perform the sampling clock synchronization efficiently and quickly. The simulation results show that when the SNR (Signal-to-Noise) is 25dB, the MSE (mean square error) of 1IMO (one-input multi-output) system is about 0.5e-4 lower in AWGN channel than in multi-path channel; each receiver antenna is added, the MSE will decline about 0.1e-4; the performance of 2IMO (two-input multi-output) system is worse than HMO system, the MSE is about 0.3e-4 lower. |

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.
