Robust MMSE Transceiver Designs for Downlink MIMO Systems with Multicell Cooperation
Figure 1
System configurations of two multicell examples: (a) 3 eNBs and 3 UEs. (b) 3 eNBs and 6 UEs. The coordinates of relevant eNBs and UEs shown here are employed for simulations. Note that UE1 is right on the edge of three cells in both systems. In example 3, UE is near the cell edge between cells 1 and 3. In example 4, UE and UE are near the cell edge between cells 1 and 3, and UE and UE are near the cell edge between cells 2 and 3. (Legends: Each UE is associated with the eNB in the same color.)
