摘要

本文分析了单音频率估计方法,采用脉冲对法对迭代滤波方法进行简化。对该算法进行了统计分析,并在加性高斯白噪声和彩色噪声存在的情况下进行了仿真。仿真结果表明,该算法在上述两种环境下都能渐近地实现CRB,即使在短数据长度下也能有效地执行。

Frequency estimation method based on iterative filtering and pulse-pairs
This paper analyzed the single tone frequency estimation method, using pulse pairs method to simplify the iterative filtering method. Statistical analysis of this algorithm is given and simulation is carried out in the presence of additive white Gaussian noise and colored noise. Through simulation, this algorithm is shown to be able to achieve CRB asymptotically in both environment mentioned above and perform efficiently even at short data length.
