Abstract :
In this paper, we discuss some properties of linear estimation based upon transformed measurements. A necessary and sufficient condition on the measurement transformation, such that the estimate based upon the transformed measurements is the same as the estimate based upon the original measurements, is given. Problems of this kind often arise in applications such as data compression, distributed signal processing, and fixed-interval smoothing.
