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。
The research contents mainly consist of symbol rate estimation, carrier frequency offset estimation, modulation recognition and blind demodulation.
研究内容主要包括:符号率估计、载波频偏估计、调制方式识别以及盲解调等。
