Below a threshold signal-to-noise ratio (SNR), the mean squared error (MSB) performance of nonlinear maximum-likelihood (ML) estimation degrades swiftly. Threshold SNR prediction for ML signal parameter estimation requiring intermediate estimation of an unknown colored noise covariance matrix is facilit...

Root Mean Squared Logarithmic Error Lossytrue
In 2005, Yatracos constructed the estimator S22 = c2S2, c2 = (n + 2)(n 1)[n(n + 1)] 1, of the variance, which has smaller mean squared error (MSE) than the unbiased estimator S2. In this work, the estimator S21 = c1S2, c1 = n(n 1)[n(n 1) + 2] 1, is constructed...
