In a multiuser (MU) multiple antenna system (MAS), a subspace processor is communicatively coupled to a plurality of geographically distributed transceivers by a network. The subspace processor multiplies a plurality of data symbols in each bin of an invertible transform with spatial-processing weights to produce weighted data symbols, which are transmitted from a plurality of geographically distributed transmitters to a plurality of receivers. The spatial-processing weights are generated from channel state information in the MU-MAS to cause a desired signal to be reinforced and at least one undesired signal to be suppressed at each of the plurality of receivers.
