TRANSMIT-REFERENCE METHODS IN SOFTWARE DEFINED RADIO PLATFORMS FOR COMMUNICATION IN HARSH PROPAGATION ENVIRONMENTS AND SYSTEMS THEREOF
First Claim
1. A method for adaptive Radio Frequency (RF) jamming, the method comprising:
- 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,wherein the directional countermeasure signal is adaptively generated in real-time according to a bandwidth of the undesired signals, the bandwidth of the undesired signals being in a range from a narrow bandwidth to an ultra-wide bandwidth (UWB),wherein the directional countermeasure signal is sent by a directional antenna that directs the directional countermeasure signal towards a source of the undesired signals.

Abstract
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.
