The present invention is a method for tactical spectrum harvesting via a cognitive communication device. The method may include monitoring a wireless communication frequency spectrum. The method may further include detecting active net communication transmissions. The active net communication transmissions may be transmitted via the monitored communication frequency spectrum by a plurality of active transmitting nets. The method may further include determining an identity of/identifying at least one active transmitting net included in the plurality of active transmitting nets. The method may further include synchronizing an internal time reference of the cognitive communication device with a time reference(s) of the identified active transmitting net(s). The method may further include determining an estimated future spectral occupancy for the identified active transmitting net(s) based on time data for the active net communication transmissions, cryptographic key data for the active transmitting nets, and algorithm data for the active transmitting nets.

Tactical spectrum harvesting

A system for reducing operational power and weight of an unmanned aerial device's payload may include a frequency detection sensor for detecting a radio frequency signal within a first frequency range. A modulation detection and waveform classification module may be coupled to the frequency detection sensor for detecting a communication type associated with the first frequency range upon the frequency detection sensor detecting the radio frequency signal within the first frequency range. A radio may be coupled to the modulation detection and waveform classification module for transmitting the radio frequency signal, the radio frequency signal may include the communication type. The radio may be inactive until detection of the radio frequency signal, and the radio may be activated upon detection of the radio frequency signal.

System and method for reducing operational power and weight of an unmanned aerial device's payload

The present invention is directed to a radio system for providing dynamic switching between red side control functionality and black side control functionality. The system may include a control processor configured for providing the black side control functionality. The system may also include a protected core processor configured for providing the red side control functionality. The system may further include a switch configured for selectively connecting external control elements to the control processor and/or the protected core processor for allowing the control processor and/or the protected core processor to control the external control elements.

Method and implementation for supporting switchable red side or black side control options for airborne radio communication radios

A radio network having more than one radio node is disclosed having a cell broadcast system configured to broadcast network policies. The network includes a first group of radio nodes configured to receive the broadcast network policies. The first group of radio nodes is configured to both receive and send the network policies. A second group of radios receives the network policies from the first group of radios.

Method and system of supporting policy based operations for narrowband tactical radios

A method for a direct sequence spread spectrum communication system comprises encoding a first signal of data in a communication channel, embedding a second signal of data as notches in the communication channel, transmitting the first signal of data and the second signal of data concurrently and at a substantially same rate across the communication channel, receiving the communication channel, decoding the first signal of data in the communication channel to interpret the first signal of data, and bit decoding the second signal of data in the communication channel to interpret the second signal of data.
