Method of selecting receive antennas for mimo systems

A non-transitory, machine-readable storage medium, comprising executable instructions which, responsive to being executed by a processor of a multiple-input-multiple-output antenna system comprising a number of receive antennas that is greater than a number of transmit antennas, cause the processor to perform operations comprising:

• determining an operation between a plurality of pairs of receive antennas of a set of receive antennas;
• identifying a pair of receive antennas of the plurality of pairs of receive antennas based on the operation to obtain an identified pair of receive antennas;
• eliminating one receive antenna of the identified pair of receive antennas from the set of receive antennas to obtain a reduced set of receive antennas;
• and
• repeating the determining, the identifying, and the eliminating operations in response to a number of receive antennas remaining in the reduced set of receive antennas being more than the number of transmit antennas.

A multiple-input-multiple-output antenna system having wherein a number of receive antennas is greater than a number of transmit antennas, the system comprising:

• a memory that stores executable instructions;
• and
• at least one processor coupled to the memory, wherein the at least one processor, responsive to executing the instructions, facilitates performance of operations comprising:
• determining an operation between a plurality of pairs of antennas of a set of antennas;
• determining a pair of antennas of the plurality of pairs of antennas based on the operation;
• eliminating one antenna of the pair of antennas from the set of antennas, resulting in a reduced number of antennas remaining in the set of antennas;
• and
• repeating the determining of the operation, the determining of the pair of antennas of the reduced number of antennas and the eliminating operations in response to the reduced number of antennas being greater than the number of transmit antennas.
