| Abstract: |
| In order to raise the frequency efficiency in VHF/UHF band, a wireless data communication system based on OFDM technology is studied, then several tracking algorithms for OFDM synchronization are introduced and analysed. A new method of synchronization tracking is proposed. Simulation result proves that the method has not only low amount of calculation and complexity, but also good performance. |
| Key words: VHF/UHF communication system OFDM high frequency efficiency synchronization tracking |
