1. A cooperative multi-user multiple input, multiple output (MIMO) system, comprising:

  • at least one MIMO processor for pre-coding a plurality NR of data streams to generate a plurality NT of subspace-coded data streams, each subspace-coded data stream comprising a linear combination of at least some of the plurality of data streams, the linear combination based on channel state information corresponding to channels between a plurality of distributed transceiver stations and a plurality of wireless client devices;

    a network interface for communicatively coupling to the plurality of distributed transceiver stations via a network; and

    a network controller configured for sending the subspace-coded data streams to the plurality of distributed transceiver stations via the network, and coordinating the plurality of distributed transceiver stations to simultaneously transmit the subspace-coded data streams over wireless links to each of the plurality of wireless client devices, the pre-coding providing for coherently combining at least a first of the data streams at a first wireless client device while suppressing inter-user interference from at least a second of the data streams intended for at least a second wireless client device.
