  • Publication number: 20230033786
    Abstract: Systems and methods may include one or more devices associated with a relay network. In some examples, a relay device may be configured to determine, based at least partly on a control signal received from a destination device on a first carrier frequency, channel estimates for a channel between the relay device and the destination device. The device may determine, based at least partly on the channel estimates, a weighting function for transmissions from the relay device to the destination device. The device may generate baseband samples based on a down-conversion, from a second carrier frequency to a baseband frequency, of one or more incoming RF signals and apply the weighting function to the baseband samples to generate weighted baseband samples. The device may generate an outgoing RF signal based on an up-conversion of the weighted baseband samples from the baseband frequency to the first carrier frequency.

  • Publication number: 20200145056
    Abstract: A robotic near-field antenna measurement system allows for acquisition of near-field measurements on a non-canonical measurement surface. This near-field test data is transformed to a set of equivalent currents representing an antenna under test (AUT). These currents (if the equivalent surface is selected appropriately) allow for AUT diagnostics and calculation of all radiated fields. This test system provides a degree of flexibility that is not possible with conventional (canonical) near-field antenna test systems.
