摘要 提出了利用CORDIC算法实现OFDM系统中频率偏移校正,同时利用自动控制原理中的闭环控制原理对小数倍频偏进行环路滤波后的反馈调整,避免了突发噪声和信道深度衰落可能造成的不稳定。通过MatLab仿真,验证了该方法的性能。 Bring out a frequency adjustment method using CORDIC algorithm. Meanwhile via using closed-loop control method in adjustment of fractional frequency offset, we can avoid the instability caused by burst noise and deep channel degeneration. The performance of this measure is validated by simulation under MatLab.
