| Abstract: | For the system with colored measurement noise,based on the least square criterion,one recursive extended least squares is presented,which can obviously reduce the influence of the noise and advance the quality of the signal.And the estimation of the noise variance is also presented.One computation simulation example and the SNR verify the effectiveness and correctness of the proposed result. |
