摘要
提出一种适合CMMB接收机的粗载波频偏估计算法,小数倍频偏在时域中估计,整数倍频偏在频域中估计,而频偏的纠正则是在时域中完成。
In this paper,a new coarse carrier frequency offset estimation which is suitable for CMMB is proposed.The fractional part of frequency offset estimation is implemented in time domain and the integer part of that is implemented in frequency domain.The frequency offset correction is done in time domain.
