中文摘要:
      文章介绍了利用复相关估计信号平均频率的方法,并就其采样周期的选取与频率估计误差间的关系作了分析,最后给出最佳采样频率以及平均频率测量误差的实测结果。
英文摘要:
      Complex correlation method for estimating average frequency of signal is introduced in this paper.In order to reduce the influence of noise on the estimation error, the relationship between the sampling frequency and estimation error is analyzed.Optimal sampling frequency and experimental results of the estimation are also given.
