频偏估计算法利用已经完成定时同步的同一个训练序列来完成小数频偏估计和整数频偏估计。-Offset estimation algorithm uses the same timing synchronization has completed a training sequence to complete the fractional frequency offset estimation and integer frequency offset estimation.

基于CP的最大似然估计仿真图，两幅图，分别是符号定时偏差，以及频偏，从图中可以看出在符号定时估计最大处，相应的频偏估计值也是最接近的-CP-based maximum likelihood estimate simulation map, two maps, are a symbol timing offset, and frequency offset, it can be seen the figure in the symbol timing estimation is maximum,
