将基于傅立叶变换（FFT）的“迭代清除算法”用于相互临近的多线谱估计，这种算法计算简单快速，并具有超分辨率、高精度的特性。计算机仿真结果证明了它在多线谱估计方面的优良性能。
Based on the Fourier transform (FFT) “iterative elimination algorithm” for the adjacent multiline spectrum estimation, this algorithm is simple and fast calculation, and has super-resolution, high-precision features. Computer simulation results prove its excellent performance in multi-line spectral estimation.
