Covert Multi-Hop LEO Satellite Routing with Controlled Delays
​ System Model: LEO relay network covert against a terrestrial adversary Invention Summary: Current covert digital communication technologies typically attempt to achieve cyclic covertness by lowering transmit power, adding random timing jitter, or modifying waveforms, which often reduces data rates, increases system complexity, and can still...

Single Sensor Radio Scene Analysis for Packet Based Radio Signals Using 2nd and 4th Order Statistics
Invention Summary: Most existing wireless systems use static allocation of the radio spectrum with each system operating in a predefined fixed frequency band. Since the allocated spectrum is not used at all locations and at all times, this static allocation leads to creation of spectrum holes, which implies inefficient utilization of the available...
