It is possible to find out the fine timing offset by using pilot symbols phase because of linear relationship with subcarrier position index k. | |

It is in the frequency domain we compensate for the fine misalignment? I was baffled by the completely rotated constellation. I thought it is not possible to recover. Because it is not a small constant rotation. | |
