Abstract:
1. A method comprising: grouping antennas on a transmitting wireless station into a plurality of antenna subgroups, wherein each of the antenna subgroups forms a virtual antenna; modulating a data stream for transmission via each antenna subgroup in a wireless channel comprising a plurality of clusters each comprising a plurality of sub-carriers; applying beamforming weights for each antenna subgroup to beamform the data stream from the respective antenna subgroups to form beamformed multiple-input multiple-output (MIMO) channels; and distributing power to the respective clusters for transmission by each of the antenna subgroups such that, for each antenna group, a particular cluster of the plurality of clusters is allocated more power than other clusters, such that the particular clusters of adjacent antenna subgroups are not the same, and such that the particular cluster that is allocated more power among the plurality of clusters transmitted from one antenna subgroup is not the same as the particular cluster that is allocated more power among the plurality of clusters transmitted from an adjacent antenna subgroup.
