The timing-error estimation based on waveform detection can be used in PSK/QAM.
基于波形检测的定时误差估计算法适用于PSK/QAM调制方式。
In addition, OFDM systems are very sensitive to the effect of timing error, to obtain a better channel estimation performance, the choice of synchronization algorithm is important.
此外，由于OFDM系统易受同步误差的影响，为了获得较好的信道估计性能，同步算法的选择对进行正确的信道估计也尤为重要。
