    Abstract: Systems, methods, and non-transitory media are provided for cross-coupling modeling and compensation. An example method can include determining one or more cross-coupling coefficients representing electrical cross-coupling between a first signal path through a component and a second signal path through the component; based on the one or more cross-coupling coefficients, determining a first modified beamforming weight for a first signal associated with the first signal path through the component and a second modified beamforming weight for a second signal associated with the second signal path through the component, wherein the first and second modified beamforming weights compensate for the electrical cross-coupling between the first signal path through the component and the second signal path through the component; applying the first modified beamforming weight to the first signal associated with the first signal path; and applying the second modified beamforming weight to the second signal associated with the second signal path.

    Abstract: Systems, methods, and non-transitory media are provided for cross-coupling modeling and compensation. An example method can include determining one or more cross-coupling coefficients representing electrical cross-coupling between a first signal path through a component and a second signal path through the component; based on the one or more cross-coupling coefficients, determining a first modified beamforming weight for a first signal associated with the first signal path through the component and a second modified beamforming weight for a second signal associated with the second signal path through the component, wherein the first and second modified beamforming weights compensate for the electrical cross-coupling between the first signal path through the component and the second signal path through the component; applying the first modified beamforming weight to the first signal associated with the first signal path; and applying the second modified beamforming weight to the second signal associated with the second signal path.
