The system uses time-frequency tracking loops to extract phase errors from data subcarriers with frequency interpolation to compensate for the estimated carrier frequency offsets.
该方法使用了时频同步跟踪环路，从数据子载波提取相位误差，并利用频域插值补偿多个用户的估计频偏。
In OFDMA, closely spaced multiple subcarriers are assigned to different users for parallel data transmission.
在OFDMA中，相临的多个子载波被分配给不同的用户来为用户并行低速传输数据。
In practical OFDM systems, virtual subcarriers are usually used to avoid the transmitted data being distorted by the low-pass filter on the transmitter side.
实际的OFDM系统通常会使用虚拟子载波，以此来避免发送信号受到发送端成形低通滤波器的影响。
