N2 - A matrix formulation is used to derive the optimal least-squares coefficients and frequency response of the ALE or the D-step predictor, for sinusoids (real or complex) in additive colored noise. Several cases are considered; in low-pass background noise the amplitude gain of the sinusoids becomes essentially a monotonically increasing function of their frequency, and a decreasing function for high-pass noise. For the whitening application, signal to noise ratio (SNR) bounds of the output are derived when the input is a white signal plus a sinusoidal interference. This performance is achievable using (possibly complex) exact least-squares recursions.
