| 摘 要： | 该文介绍了高阶谱分析的基本原理及其中应用最广的双谱。通过对脑电信号的采集并进行双谱分析的实验表明，高阶谱在处理非线性和抑制高斯噪声等方面具有以二阶统计量为基础的功率谱所不具备的优越性。

| Abstract: | The basic theory of Higher Order Spectral Analysis and the most generally used Bispectrum are introduced in the paper. By certain experiments of EEG signal acquisition and bispectrum analysis, it is showed that the Higher Order Spectrum has an advantage over power spectrum, which is based on Second Order Statistics, in processing nonlinear signal and restraining Gauss noise signal. |
