Abstract
Official abstract text for this publication.
A method for adaptive Radio Frequency (RF) jamming according to one embodiment includes dynamically monitoring a RF spectrum; detecting any undesired signals in real time from the RF spectrum; and sending a directional countermeasure signal to jam the undesired signals. A method for adaptive Radio Frequency (RF) communications according to another embodiment includes transmitting a data pulse in a RF spectrum; and transmitting a reference pulse separated by a predetermined period of time from the data pulse; wherein the data pulse is modulated with data, wherein the reference pulse is unmodulated. A method for adaptive Radio Frequency (RF) communications according to yet another embodiment includes receiving a data pulse in a RF spectrum; and receiving a reference pulse separated in time from the data pulse, wherein the data pulse is modulated with data, wherein the reference pulse is unmodulated; and demodulating the pulses.
First claim
Opening claim text (preview).
What is claimed is: 1. A Radio Frequency (RF) communications system, comprising: a satellite uplink base station, wherein the satellite uplink base station comprises: a router; a power supply configured to provide power to the satellite uplink base station; and a broadband global area network (BGAN) satellite uplink configured to maintain a satellite uplink connection while the satellite uplink is in motion, wherein the BGAN satellite uplink is operatively coupled to the rout…
