Stealth Communication Via Smart Ultra-Wide-Band Signal in 5G, Radar, Electronic Warfare, etc.

To meet cybersecurity and privacy needs, “Stealth Communication” (SC) is a new approach to enable information transmission with a very low probability of being detected or interfered with. A wireless SC requires that the operating RF signal be smart, Ultra-Wide-Band (UWB), in full-fledged spatial waveform, and mimics noise. “Communication” here is broad-scoped, encompassing electronic warfare (EW), radar, communications, etc. For terrestrial 5G wireless, MIMO (Multiple-Input Multiple-Output) is needed. Empirical study on implementation of SC in 5G has produced promising results, especially for the early-bird 5G which operates at frequencies below 11 GHz only.
