Abstract:Total least-squares method is preferrable to estimate the parameters in the linear observation models when both the observaion and designed matrix are contaminated by random errors.However,the conventional total least-squares solution cannot deal with the ill-posed problems,so the regularization algorithm must be used in this case.The formulas of regularized total least-squares solution based on Tikhonov regularization criterion are derived and the variance-covariance matrices of the estimated parameters ar...
Keywords:total least-squares solution  ill-posed model  Tikhonov regularization  designed matrix  random error
