Carrier Frequency Error的意思|示意

The orthogonal multicarrier modulation, which is the main character of OFDM, determines that it is very sensitive to both timing synchronization error and carrier frequency offset.

OFDM系统自身的正交多载波调制特点，决定了其对定时误差和载波频率偏差十分敏感。

A single carrier modulation scheme suitable for use in high frequency communication systems is provided that achieves improved residual frequency error and phase noise estimation.
