提出了一种基于频域插值的阻尼正弦信号参数估计方法。插值算法利用离散傅里叶变换(DFT)结果的三个峰值来估计阻尼因子和信号频率。该方法在频域插值过程中完全消除了负频点频谱泄漏的影响,具有较高的插值精度。通过对不同算法的比较,验证了该方法的有效性.
This article propose a parameter estimation method for of a damped sinusoidal signal by the frequency domain interpolation. The three peaks of the discrete Fourier transform (DFT) result are used in the interpolation algorithm to estimate the damping factor and signal frequency. The proposed method can achieve a high accuracy because the influence of spectrum leakage from negative frequency are completely removed during the frequency domain interpolation. The comparison of different algorithms are discussed, which confirm the effectiveness of the proposed method.
