METHOD OF SELECTING RECEIVE ANTENNAS FOR MIMO SYSTEMS

摘要

Aspects of the subject disclosure may include, for example, a device, process or software that determines an operation between a number of pairs of antennas of a set of antennas. A pair of antennas of the number of pairs of antennas is determined based on the operation. One antenna of the pair of antennas is eliminated from the set of antennas, which results in a reduced number of antennas remaining in the set of antennas. Each of the determining of the operation, the determining of the pair of antennas of the reduced number of antennas and the eliminating of the one antenna of the pair of antennas is repeated in response to the reduced number of antennas being greater than a predetermined number of antennas. Other embodiments are disclosed.

1. A method for managing a set of receive antennas of a multiple-input-multiple-output orthogonal frequency division multiplexing system, wherein a number of receive antennas is greater than a number of transmit antennas, comprising:
determining, by a system including a processor, an amount of mutual information between pairs of receive antennas in the set of receive antennas; identifying, by the system, a pair of receive antennas of the set of receive antennas based on the amount of mutual information between the pair of receive antennas to obtain an identified pair of receive antennas; eliminating, by the system, one receive antenna of the identified pair of receive antennas from the set of receive antennas to obtain a reduced set of receive antennas; calculating, by the system, a number of receive antennas of the reduced set of receive antennas; and repeating, by the system, the identifying, the eliminating, and the calculating in response to the number of receive antennas remaining in the set of receive antennas being greater than the number of transmit antennas.
