1. A communication system for multiple inputs and multiple outputs (MIMO), comprising:
- a plurality of modal antennas, each of the plurality of modal antennas operable in a plurality of modes, each mode associated with a distinct radiation pattern;
a processor configured to select one of the plurality of modes for each of the plurality of modal antennas during a time interval based at least in part on a channel quality indicator (CQI);
wherein during the time interval, for each of the plurality of modal antennas, the processor is configured to determine a CQI improvement for each of the plurality of modes;
wherein during the time interval, the processor is configured to select one of the plurality of modes for each of the plurality of modal antennas based at least in part on the CQI improvement for each of the plurality of modes and an envelope correlation effect,wherein the CQI improvement for each mode is determined based at least in part on a predicted CQI of the mode relative to a predicted CQI for each of the other modes in the plurality of modes.

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.
