SVD-TLS和LS方法估计AR模型功率谱,假定仿真的观测数据由 产生，其中w(n)是一高斯白噪声，其均值为0，方差为1，并取n=1,…..,128，这里分别用LS方法和SVD-TLS方法估计观测数据的AR模型参数。-SVD-TLS and the LS method to estimate AR model for power spectrum, assuming that the simulation produced by the observed data, where w (n) is a Gaussian white noise with mean 0 and variance 1, and take n = 1, ... .. , 128, LS methods were used here and SVD-TLS method to estimate the AR model parameters observed data.
