1. A multi-input multi-output (MIMO) antenna processing system, comprising:

  • a first automatic tuning module configured to communicate first voltage signals to active components associated with a first modal antenna;

    a second automatic tuning module configured to communicate second voltage signals to active components associated with a second modal antenna;

    each of the first and second automatic tuning modules being coupled to an adaptive processor, and each of the first and second automatic tuning modules being further coupled to a lookup table;

    the adaptive processor further coupled to each of a first circuit block and a second circuit block;

    the first circuit block coupled to a first comparator and first counter, the first comparator configured to receive inputs from the first circuit block and compare with a reference voltage communicated to the first comparator from the adaptive processor, the first counter is configured to receive a first comparator output signal from the first comparator, and a first counter output of the first counter is configured for communication with the first automatic tuning module and the lookup table associated; and

    the second circuit block coupled to a second comparator and second counter, the second comparator configured to receive inputs from the second circuit block and compare with a reference voltage communicated to the second comparator from the adaptive processor, the second counter is configured to receive a second comparator output signal from the second comparator, and a second counter output of the second counter is configured for communication with the second automatic tuning module and the lookup table associated;

    wherein the first voltage signals associated with the first automatic tuning module are determined from the lookup table based on a combination of the first counter output signal, a first output signal associated with the adaptive processor, and a first bi-directional signal associated with the first automatic tuning module; and

    wherein the second voltage signals associated with the second automatic tuning module are determined from the lookup table based on a combination of the second counter output signal, a second output signal associated with the adaptive processor, and a second bi-directional signal associated with the second automatic tuning module.
