Figure 6From: Interference Mitigation by Practical Transmit Beamforming Methods in Closed FemtocellsThe outage rate without transmit beamforming (dotted curve), (dashed curves), and (solid curves) as a function of when mode 1 over two ("" markers) and four ("o" markers) antennas is used. The outage probability is 0.1 and mean SNR value of the serving cell signal () is 10 dB.Back to article page
