| 摘 要： | 正交频分复用(OFDM)技术已经成为当今高速无线通信系统的研究热点.但OFDM系统的显著问题是对频率偏移十分敏感.文中采用最大似然估计算法(MLE)进行频偏估计,并在其基础上提出了一种简化算法,该算法可大大降低运算的复杂度.

| Abstract: | Nowadays, orthogonal frequency division multiplexing has become a research hotspot of high speed wireless communication system. However, the notable problem of OFDM system is its sensitivity to frequency offset. Maximum Likelihood Estimation was used to estimate the frequency offset in this article. On the basis of this, a simplified method, which could reduce computational complexity significantly, was proposed. |
