1. A system for generating orthogonal frequency division multiplexing (OSDM) reuse signals, the system comprising:

  • a first beamforming assembly comprising;

    a first signal source configured to provide a first signal;

    a first low noise amplifier communicatively coupled with the first signal source and configured to amplify the first signal;

    a first power divider communicatively coupled with the first low noise amplifier; and

    a first beamformer;

    a second beamforming assembly comprising;

    a second signal source configured to provide a second signal;

    a second low noise amplifier communicatively coupled with the second signal source and configured to amplify the second signal;

    a second power divider communicatively coupled with the second low noise amplifier; and

    a second beamformer;

    wherein the first and second power dividers are each communicatively coupled with the first and second beamformer, and wherein the first power divider is configured to divide the amplified first signal into a first beamformer component for sending to the first beamformer and a second beamformer component for sending to the second beamformer, and the second power divider is configured to divide the amplified second signal into a first beamformer component for sending to the first beamformer and a second beamformer component for sending to the second beamformer; and

    wherein the first beamformer includes program means for combining, based on a total array size of the first beamforming assembly and the second beamforming assembly, the received first beamformer components of the first signal and second signal into a first combined signal, and the second beamformer includes program means for combining, based on the first distance, the received second beamformer components of the first signal and second signal into a second combined signal, the first and second combined signals having one or more of a shared frequency, a shared signal polarization, and a shared coverage area, the first and second combined signals formed such that, when the combined signal is received, an additive array factor is provided resulting in a peak in one of the first signal and the second signal and a null on the other of the first signal and second signal.
