Abstract
The Synchronization technology for OFDM is an important factor that affects the system capability. In this paper, an improved training symbol with symmetric and repetitive structure is proposed, and the estimate range of the frequency offset is enlarged by increasing the number of repetitive sequence and shortening the interval of repetitive sequence. The symmetric property of the training symbol and the correlation property of the PN weighted factor are utilized in the timing offset estimation to improve the accuracy.
