This paper deals with the blind identification of the variances of the additive noises in a two-channel SIMO system. They are estimated by using a frequency domain errors-in-variables scheme, when finite impulse responses (FIR) filters are driven by a white input sequence. It should be noted that the proposed approach has the advantage of addressing the unbalanced case, i.e. when the noise variances...
This paper deals with the issue of correlated noises in GPS navigation. GPS is based on the measure of the propagation delays of satellite signals. Therefore, additional delays induced when traveling through the ionosphere or the troposphere degrade GPS accuracy. These error sources are correlated, both spatially and temporally. Thus, when using an extended Kalman filter as navigation algorithm, these...
