| Abstract: | In this paper, the estimator is based on a linear transformation of the LS estimation.It provides an optimal solution to the true and a constrained covariance matrix. The regularization techniques are unified with the respect to filtering factors. Filtering factors and corresponding eigenvalue of error covariance matrix of some known regularization estimators as Tikhonov-Philips regularization, truncated singular value decomposition, generalized ridge regression and others are provided. |

| Keywords: | LS estimation covariance matrix regularization filtering factor |
