This letter proposes a two-points non-iterative IpDFT algorithm for parameter estimation of the damped real-valued sinusoidal signal, which is named as the I2pNDFT. Both long- and short- range leakages are compensated to estimate the parameters accurately. Simulation results prove the effectiveness of our methodmagenta, compared with other IpDFT methods.

精确估计阻尼因子和频率的两点插值DFT算法

这封信提出了一种用于阻尼实值正弦信号参数估计的两点式非迭代IpDFT算法，称为I2pNDFT。长距离和短距离泄漏均得到补偿，以准确估算参数。仿真结果证明，与其他IpDFT方法相比，我们的洋红色方法是有效的。
