How to create pseudoredundant measurements

In a previous paper we showed, that it is possible to increase the information of the measurement vector by extending the available number of measurements in the measurement vector y(k) with additional measurements. Theoretical considerations proved, that the additional measurements do not contain any new information, but information in another for, i.e. in another coordinate system. This new coordinate system is generated by a mapping of the original components of the measurement vector into the additional components. In this paper we are going to occupy ourselves with the restrictions and the preliminaries of such additional measurements. Therefore we will look at information in the possible mappings and we will give some hints how to create the optimal extension of the measurement vector.
