这是篇一种利用PN序列的OFDM频率同步，觉得很有用，与大家共同享用。-this chapter is a use of the PN sequence OFDM frequency synchronization, feel useful, and we enjoyment.

This paper considers semiblind channel estimation and data detection for orthogonal frequency-division multiplexing (OFDM) over frequency-selective fading channels.

ofdm系统的仿真实现 加入导频 训练序列 小数倍频偏估计-Join ofdm system simulation pilot training sequence to achieve a small multiple of the frequency offset estimate

OFDM is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method. A large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels.
