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.
Claims18
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 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;
- wherein the selecting during a time interval comprises:
- for each of the one or more active modules,
- 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 based on the predicted CQI of each of the plurality of modes minus the predicted CQI of the selected mode.
A configurable circuit capable of reconfiguration about a plurality of potential states, comprising:
- one or more active modules, wherein each of the one or more active modules is adapted to be configured in a plurality of modes;
- a processor adapted to communicate control signals to each of the one or more active modules;
- said processor configured to select a mode among the plurality of modes of each of the one or more active modules to optimize signal quality for each time interval based on a channel quality indicator (CQI);
- and
- wherein a selected mode for each of said active modules is configured by said processor by communicating said control signals to said active modules;
- wherein during a time interval, for each of the one or more active modules, the processor is configured to measure an instantaneous CQI of the selected mode, obtain a predicted CQI of each of the plurality of modes, and obtain a CQI improvement for each of the plurality of modes,
- wherein the CQI improvement is based on the predicted CQI of each of the plurality of modes minus the predicted CQI of the selected mode.
