Abstract
Methods and devices for use with a multi-feed antenna used in a MIMO communication system are described herein. A method can include obtaining an antenna feed characteristic indicator associated with each of the feeds of the multi-feed antenna, and controlling how power is distributed among the feeds based on the antenna feed characteristic indicator associated with each of the feeds. An antenna feed characteristic indicator can be, e.g., an indicator of impedance matching, in which case power can be distributed among the feeds of the multi-feed antenna based on the indicators of impedance matching associate with each of the feeds. Power can also be distributed based on an indicator of link quality. Additionally, or alternatively, coding rate and/or modulation type can also be controlled for each of the feeds of the multi-feed antenna, based on one or more antenna feed characteristic indicators and/or one or more indicators of link quality.
