摘要

我们提出了一种定位谱线的方法，当信噪比很小时，谱线在周期图(功率谱)中被彩色背景噪声遮挡。这个过程可以完全自动化，而且大部分(如果不是全部的话)计算都可以在频域中完成。

Estimating a sinusoid in low SNR coloured noise

We propose a procedure for locating a spectral line, when the signal to noise ratio is so small that the line is obscured in the periodogram (power spectrum) by the coloured background noise. The procedure can be totally automated, and most, if not all, of the computations can be done in the frequency domain.
