Signal enhancement using canonical projection operators

A commonly occurring signal processing application is concerned with the task of resurrecting a signal from a noise and distorted measurement of that signal. It is often known that the underlying signal possesses well-defined properties which are obscured through the measurement process. A signal enhancement algorithm is herein developed which slightly modifies the measured signal so that the modified (or enhanced) signal takes on these prescribed properties. As such, the modified signal often provides a more accurate characterization of the underlying signal.
