Abstract
Interference is reduced with a multiple-input-multiple-output (MIMO) system having a set of basestations including a first basestation and a second basestation is reduced. Signals associated with the first basestation having its own antenna elements are received. The first basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the first basestation is uniquely associated with a mobile station associated with the first basestation. Signals associated with the second basestation having its own antenna elements are received. The second basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the second basestation is uniquely associated with a mobile station associated with the second basestation. Signals associated with the first basestation are jointly detected in conjunction with the signals associated with the second basestation to produce a set of detected signals.
