Abstract: A system to deterministically and dynamically prevent interference to the operation of safety-of-life radio equipment in a vehicle is provided. The system includes a radio management system and a wireless network frequency controller communicatively coupled to the radio management system. The wireless network frequency controller is operable to restrict the operational frequency of any one or more of internal wireless communication devices and any one or more of wireless sensors that are communicatively coupled to the wireless network frequency controller. The restriction of the operational frequency is based on input from the radio management system. The restriction of the operational frequency ensures that all the safety-of-life radio equipment has interference-free operation with the internal wireless communication devices and the wireless sensors that are communicatively coupled to the wireless network frequency controller.

Abstract: A method to increase throughput over a very high frequency aeronautical network is provided. The method comprises simultaneously receiving at least two downlink signals at a plurality of ground antennas at an aeronautical ground station of the very high frequency aeronautical network, generating a channel-state-information matrix based on preambles, decomposing the simultaneously received at least two downlink signals into respective ones of the at least two downlink signals, and decoding each of the respective ones of the decomposed at least two downlink signals. The at least two downlink signals include respective preambles indicative of a channel state. Solutions to the channel-state-information matrix are generated by a mean-square-error algorithm to avoid singularities in the solutions. The decomposing of the simultaneously received at least two downlink signals is based on the generated channel-state-information matrix.

Abstract: In one embodiment, a method of controlling intermodulation (IM) interference is provided. The method comprises determining if an IM product spectrum overlaps the spectrum of an assigned receive frequency and determining when transmissions from at least two transmitters are to overlap in time. If the IM product spectrum overlaps the assigned receive frequency spectrum, it is determined if a signal is being propagated on the receive frequency when the transmissions from the at least two transmitters are to overlap in time. If a signal is not being propagated on the receive frequency, the at least two transmitters are allowed to transmit the overlapping transmissions; and if a signal is being propagated on the receive frequency, control steps are initiated to reduce the effects of IM interference.
