代码说明:

  函数作用: cwstd.m——用综合标准化法标准化矩阵 Cwfac.m——计算相关系数矩阵,计算特征向量和特征值,对主成分进行排序,计算各个特征值的贡献率,挑选主成分(贡献率达与85 ),输出主成分个数,计算主成分载荷 Cwscore.m——计算各主成分得分,综合得分并排序 Cwprint.m——读入数据文件,调用以上三个函数,并输出结果 原始数据:存储在src.txt中是一个30×8的矩阵 敲入命令: (PCA)

    构造一组输入为白噪声加三个频率非常接近的正弦波,其信噪比为10dB,观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率,并比较结果。(constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.)
