SVDTLS
用Matlab仿真实现最小二乘法和总体最小二乘法估计
假设仿真的观测数据 产生,其中 为0均值, 单位方差的高斯白噪声,取n=1,2,....128。
试用TLS,取AR阶数为4,估计AR参数 和正弦波频率;再用SVD-TLS ,估计AR参数 和正弦波频率。
(1)、在仿真中,AR阶数取为4和6。
(2)、执行SVD-TCS时,AR未知。仿真运行至少二十次。
(Simulation using Matlab and the overall least squares least squares estimate assumptions simulated observation data are generated, where 0 mean, unit variance Gaussian white noise, take n = 1,2 ,.... 128. Try TLS, take AR order of 4, estimated AR parameters and the sine wave frequency then SVD-TLS, estimated AR parameters and the sine wave frequency. (1), in the simulation, AR order is taken as 4 and 6. (2), when the implementation of SVD-TCS, AR is unknown. Simulation run at least twenty times.)

LS
说明: the linear ARX model as shown below [12] is used to represent the input and the output data for the system. This ARX model is utilized for both Least Square (LS) and Recursive Least Square (RLS) algorithms. It is one of the simplest statistical methods for system identification used to find the transfer function for the model. The equations given by [15]:
Y=φβ+ξ (7)
β=〖(φ^T φ)〗^(-1) φ^T Y (8)
where Y is the predicted output. φ is includes actual input and output parameters. β is includes parameters to be estimated.
