Patent ID: 7844240

Claim:
A non-transitory computer readable medium comprising computer program instructions capable of being executed in a processor and defining the steps comprising: executing a determination operation for each antenna of a set of antennas comprising executing a correlation operation for a MIMO system according to the formula: Corr ⁡ ( k , l ) =  〈 h k  h k  2 , h l 〉  where X={1, 2 . . . K}, h k is the kth row of channel matrix H, h l is the lth row of channel matrix H, k≠l, and k, lεX; deleting at least one of said antennas from said set of antennas based on said determination operation; and performing said deleting until the number of antennas remaining in said set of antennas equals a desired number of antennas.
