基于CP的STO估计，其中包含有利用相关性的基于CP的估计和利用差值基于CP的估计。-STO is estimated based on the CP, which includes the use of estimates and use the difference between correlation CP CP based on estimates.

OFDM系统中STO不仅能引起相位失真，而且能引起ISI,利用相关性做基于CP的STO估计。-STO for OFDM systems can not only cause phase distortion, and can cause ISI, to make use of relevant based on the CP STO estimates.
