Envelope-constrained filters with uncertain input
Evans RJ., Cantoni A., Ahmed KM.
In an envelope-constrained filtering problem with uncertain input the set of possible input waveforms and the set of permissible output waveforms are each defined by envelope constraints (time domain inequalities). The object is to find the optimal (minimal norm) inpulse response for which every waveform in the input envelope evokes a response in the output envelope. The problem is solved by extending earlier results for a single specified input. The solution is further extended to allow for unknown-but-bounded errors in the filter realization. © 1983 Birkhäuser Boston, Inc.
