Abstract :
In some signal reconstruction problems, the observation equations can be used as a priori information for selecting the best combination of observations before acquiring them. In the present correspondence, the authors define a selection criterion and propose efficient methods for optimizing the criterion with respect to the combination of observations. The examples illustrate the value of optimized sampling using the proposed methods
