A mean-squared-error condition for weighting ionospheric delays in GNSS baselines

چکیده
Abstract Although ionosphere-weighted GNSS parameter estimation is a popular technique for strengthening estimator performance in the presence of ionospheric delays, no provable rules yet exist that specify needed weighting dependence on circumstances. The goal present contribution therefore to develop and conditions need be satisfied order solution mean squared error (MSE) superior ionosphere-float solution. When satisfied, presented guarantee from an MSE view, when (a) ionosphere-fixed can used, (b) must or (c) used.

متن کاملCompetitive Mean-Squared Error Beamforming
Beamforming methods are used extensively in a variety of different areas, where one of their main goals is to estimate the source signal amplitude s(t) from the array observations y(t) = s(t)a + i(t) + e(t), t = 1,2,..., where a is the steering vector, i(t) is the interference, and e(t) is a Gaussian noise vector [1, 2]. To estimate s(t), we may use a beamformer with weights w so that s(t) = w*...
متن کاملOptimal Mean Squared Error Imaging
The problem of forming images that are optimal with respect to a Mean Square Error (MSE) criterion, based on nite data, is considered. First, it is shown that the MSE criterion is consistent with the general goal of classifying images, in that decreasing the MSE guarantees a decrease in the probability of misclassifying an image. The problem of choosing sampling locations for image formation th...
متن کاملMean-Squared Error Beamforming for Signal Estimation: A Competitive Approach
Beamforming is a classical method of processing temporal sensor array measurements for signal estimation, interference cancellation, source direction, and spectrum estimation. It has ubiquitously been applied in areas such as radar, sonar, wireless communications, speech processing, and medical imaging (see, for example, [1, 2, 3, 4, 5, 6, 7, 8] and the references therein.) Conventional approac...

Let be a random sample from a normal distribution with unknown mean and known variance The usual estimator of the mean, i.e., sample mean is the maximum likelihood estimator which under squared error loss function is minimax and admissible estimator. In many practical situations, is known in advance to lie in an interval, say for some In this case, the maximum likelihood estimator...
