  • SYSTEMS, DEVICES, AND METHODS FOR MILLIMETER WAVE COMMUNICATION FOR UNMANNED AERIAL VEHICLES
    Publication number: 20210373552
    Abstract: Systems, devices, and methods are described for controlling, and communicating with, unmanned aerial vehicles (UAVs) over a millimeter wave (mmWave) communication network established between a base station and the UAVs. A communication system may include one or more unmanned aerial vehicles (UAVs). The communication system may further include one or more base stations including millimeter wave (mmWave) antennas configured to generate control signals to the one or more UAVs over an mmWave communication network.

  • Method and apparatus for reducing interference in multiple-input-multiple-output (MIMO) systems
    Patent number: 7912014
    Abstract: Interference is reduced with a multiple-input-multiple-output (MIMO) system having a set of basestations including a first basestation and a second basestation is reduced. Signals associated with the first basestation having its own antenna elements are received. The first basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the first basestation is uniquely associated with a mobile station associated with the first basestation. Signals associated with the second basestation having its own antenna elements are received. The second basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the second basestation is uniquely associated with a mobile station associated with the second basestation. Signals associated with the first basestation are jointly detected in conjunction with the signals associated with the second basestation to produce a set of detected signals.
