摘要
利用CMMB信号中存在的伪随机序列的相关性,对CMMB信号载波同步技术中的整数倍频偏和小数倍频偏估计算法进行了研究,从而为后续的导航测距工作打下必要的基础。通过仿真验证表明,该方法具有较高的估计精度和可行性。
An algorithm for the integer frequency offset and fraction frequency offset estimation, which is important in the carrier synchronization technology for CMMB（China mobile multimedia broadcasting）, is studied by using the correlation of the pseudorandom sequence in CMMB signal, so as to lay a foundation for the following work of navigation/ranging. Simulation results show that the algorithm is of higher accuracy and is feasible.
