  • Patent number: 11984951
    Abstract: Systems and methods for adaptive beamforming for a mobile satellite system (MSS). Embodiments described herein provide individual-user-optimized, adaptive beamforming. One example system creates a user beam optimized based either on known user locations or the waveforms received from all cochannel users. The user beam maximizes the signal-to-interference-noise relative to the desired user, both in the forward and return links. The optimization process considers the spatial distribution of all cochannel users in the footprint of the satellite. The user beam adapts to the user's location and co-channel interference environment.

  • Patent number: 11606798
    Abstract: A terrestrial communication systems, specifically a signal collision avoidance system between a terrestrial transmitter and an airborne receiver, is disclosed. The terrestrial communication system includes an electronic processor configured to determine a receive frequency from a nearby airborne receiver, determine a transmit frequency from a communicatively coupled terrestrial transmitter, and modify the transmit frequency of the terrestrial transmitter based on the determined receive frequency and transmit frequency. To modify the transmit frequency, the electronic processor compares the receive frequency and the transmit frequency to determine a channel type. Based on the determined channel type, including co-channel and adjacent-channel, the electronic processor modifies a spectrum signature of the transmit frequency so that the transmit frequency does not interfere with the receive frequency of the airborne receiver.
