对此，给出了计算时间不同步量的方法，使数据经时间不同步误差修正后可用；

An algorithm for the asynchronous time is presented and then the mended data can be usually utilized.

在上行链路中每个用户由于载波频率偏差而存在潜在的不同步，这样使子载波之间失去正交性，从而在基站接收端产生多用户间干扰。

However in uplink channel, each user has its own frequency offset which leads to a loss of orthogonality among the sub-carriers and multiuser interference at the base station receiver.
