Abstract
A system and method for optimizing the performance for MIMO are provided, the system including multiple antennas, including at least one modal antenna, wherein each of the at least one modal antenna has multiple modes corresponding to multiple radiation patterns, and a processor coupled to the multiple antennas and configured to select a mode among the multiple modes to optimize signal quality for each time interval based on a CQI by considering envelop correlation effects.

A computerized method for selecting an optimum state for a configurable circuit capable of selective configuration about a plurality of potential states, comprising:
- providing one or more active modules in the circuit, wherein each of the one or more active modules is adapted to be configured in a plurality of modes;
- and
- selecting a mode among the plurality of modes for each of the one or more active modules to optimize signal quality for each time interval based on a channel quality indicator (CQI);
- wherein the selecting during a time interval comprises:

- measuring an instantaneous CQI of the selected mode;
- obtaining a predicted CQI of each of the plurality of modes;
- and
- obtaining a CQI improvement for each of the plurality of modes;
- wherein the CQI improvement is defined as the predicted CQI of each of the plurality of modes minus the predicted CQI of the selected mode;
- wherein the selected modes of the one or more active modules collectively define a state of the circuit, and
- wherein said circuit in said optimum state is adapted to produce an optimum signal.

- further characterized in that:
- said determining an optimum signal comprises:
- comparing a first signal with each of the remaining signals of said plurality of signals to determine a CQI improvement for each of the remaining signals, wherein the CQI improvement is defined as a difference between the CQI of a signal of the remaining signals minus the CQI of the first signal;
- if at least one of said remaining signals has a positive CQI improvement when compared to the first signal, selecting the optimum signal of the remaining signals for output, wherein the optimum signal comprises the greatest CQI improvement over the first signal;
