通过将其与秩一相位估计法联合使用，克服了秩一法对初始值敏感的缺点，提高了补偿算法的精度和效率。

By combining it with the rank one phase estimation algorithm, improvement of both accuracy and efficiency can be obtained by overcoming the weakness that ROPE is sensitive to initial value.

首先，本文从信号参数(幅度、频率、相位)估计入手，研究了直接法、细化频谱法和高精度FFT法等算法。

First of all, starting with the estimate of signal parameter (e. g. amplitude, frequency and phasic), it makes a research in algorithms of direct, subdivide the spectrum, high-precision FFT and so on.
