    摘要: 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.

    摘要: 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.

    摘要: 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.
