Patent ID: 8014461

Claim:
A base station 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; 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 to receive the symbol data for its corresponding group of subchannels from each of the plurality of front end processors; and a plurality of back end processors associated with a plurality of groups of spatial streams, wherein each of the back end processors is associated with at least one group of spatial streams, wherein each of the at least one group of spatial streams corresponds to one or more spatial division multiple access (SDMA) users, wherein each of the plurality of AAS processors is coupled to each of the plurality of back end processors, and wherein each of the plurality of back end processors is configured to process symbol data for one or more SDMA users, 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 the symbol data of each subchannel and wherein during receive processing, each of the plurality of AAS processors is configured to output the weighed symbol data to the back end processors such that each of the plurality of back end processors receives the adaptively weighed symbol data for one or more corresponding SDMA users from one or more of the plurality of AAS processors.
