摘要 针对空频-OFDM(SF-OFDM)系统,本文给出了一种快速的同步方法。通过前后连续的两个训练符号,得出了一种适用于SF-OFDM系统的联合频率粗同步和符号细同步的估算方法。最后计算机仿真结果表明本文所给算法是有效的。 A fast synchronization method is presented for a Space-frequency OFDM (SF-OFDM) system. Using two consecutive training symbols, a method for the joint estimation of fine timing and coarse frequency-offset is obtained. Finally, through computer simulation, the methods we proposed are verified.
