Abstract:
1. An apparatus comprising: a plurality of adaptive antenna signal (AAS) processors associated with a plurality of groups of subchannels, wherein each AAS processor is assigned to process symbol data of a corresponding group of subchannels, wherein each group of subchannels includes a plurality of subchannels, and wherein subchannels of an individual group are different from subchannels of other groups; and a plurality of front end processors, wherein each of the plurality of AAS processors is coupled to each of the plurality of front end processors, wherein each of the plurality of front end processors is configured to receive and process signals from a corresponding group of antennas and output symbol data for subchannel groups, and wherein each of the plurality of AAS processors is configured to receive the symbol data for its corresponding group of subchannels from each of the plurality of front end processors, wherein each of the plurality of AAS processors is configured to process symbol data of its corresponding group of subchannels, including configuration to apply adaptive weights to symbol data of each subchannel and output the adaptively weighted symbol data for one or more spatial division multiple access (SDMA) users.
