Abstract:
1. A method comprising: determining, by a system comprising a processor, a plurality of correlations between different rows of a channel matrix associated with a set of receive antennas, wherein each row of the channel matrix corresponds to a receive antenna of the set of receive antennas that receives a signal comprising a plurality of subcarriers, and wherein the determining the plurality of correlations comprises determining an absolute value of an inner product of the different rows of the channel matrix averaged over the plurality of subcarriers; identifying, by the system, a pair of receive antennas based on the plurality of correlations; eliminating, by the system, one receive antenna of the pair of receive antennas from the set of receive antennas; determining, by the system, a number of receive antennas remaining in the set of receive antennas; and repeating, by the system, the identifying of another pair of receive antennas and the eliminating of one receive antenna of the another pair of receive antennas in response to the number of receive antennas remaining in the set of receive antennas being greater than a predetermined number of receive antennas.
