Synchronization Scheme Based on OFDM System in Wireless Channel
Zhen Jian-hong · Journal of Yunnan University for Nationalites · 2005
The OFDM technique has recently gained increased interest as a modulation scheme for high-speed wireless transmission. However, The principal weakness of OFDM is its sensitivity to time and frequency offsets. In this paper, a synchronization scheme based on PN sequence was presented, include symbol synchronization,carrier synchronization and sample rate synchronization. The simulation results show that it has better synchronization precision.
