Because carrier frequency offset and sample timing offset destroy the orthogonality among subcarriers, seriously degrade system performance, and then MIMO OFDM systems need perfect carrier frequency and sample timing synchronization algorithms.
由于载波频率偏移和采样钟定时误差都将导致MIMO OFDM系统子载波间失去正交性,会严重降低系统性能,因此MIMO OFDM系统需要近乎完美的载波频率同步和采样钟同步方案。

This slide deck by Pam Rostal gives the timing for each phase of the exercise and also provides some sample backlogs for the participants to use.
Pam Rostal的这一幻灯片中为练习中的每个阶段设定了时间，同时也提供了一些backlog样例供参与者使用。
Through adopting this algorithm the timing error is shortened to a half of the sample time interval.
通过采用这种算法可将定时误差缩小到只有抽样时间间隔的一半。
