The measurements used in many parameter-estimation problems are corrupted by coloured noise. When the noise covariance is unknown, which is often the case, it is desirable to select an equivalent white noise which will give meaningful variances for the parameters estimated. This paper derives an expression for this equivalent white noise and gives the results of applying the method to a parameter-estimation problem.
