摘要
结合中国移动多媒体广播(CMMB)信道的帧结构和调制方式,利用不同数据码元间共轭相乘的算法来完成整数倍频偏(IFO)的捕获。最后采用最小二乘估计法捕获采样频偏和残余频偏。计算机仿真验证了算法能准确地完成频偏估计。
Combining with the frame structure of China mobile multimedia broadcasting（CMMB）,this essay introduced an integer frequency offset（IFO） captured algorithm using conjugate multiplication between adjacent symbols.At last,introduced a least-squares approximation algorithm to acquire the sampling frequency offset and the residual frequency offset.The computer simulation proves that least-squares approximation can get precise results.
