| 摘 要： | 本论文主要比较了两种多用户上行链路同步估计算法—时域同步与频域同步的性能;最后提出一种新的频率补偿算法使剩余频率快速降到±0.25子载波间距左右,使得频偏估计更具鲁棒性,并说明了算法仿真的有效性。

| Abstract: | This paper discusses the multiuser OFDM uplink synchronization scheme with parameter choices and simulation results for the proposal synchronization scheme which show that the synchronization requirements are satisfied.Finaly the paper proposes a new frequency compensation algorithm which can reduce the remaining carrier frequency offset to within-0.25~ 0.25.Simulations show that the performance are satisfied. |
