摘要

在许多应用中，对通信信号载波频率的估计要求具有较高的估计精度和较宽的估计范围。提出了一种基于极大似然原理和迭代过程的高精度宽估计载波频率估计算法。通过计算机仿真，将迭代算法的性能与另外两种常用的经典载波频率估计算法进行了比较。仿真结果表明，该迭代算法具有较好的性能。

A Simple Iterative Carrier Frequency Estimation Algorithm

The estimation of carrier frequency of communication signals with high estimation precision and wide estimation range is required in lots of applications. A carrier frequency estimation algorithm based on Maximum-likelihood principle and iterative process with high precision and wide estimation range is proposed in this paper. The performance of the iterative algorithm is compared with the other two widely used classic carrier frequency estimation algorithms by computer simulations. In simulation results, the iterative algorithm has better performance than the others’.
