Figure 2From: On the user performance of orthogonal projection signal alignment scheme in MIMO relay systemsTotal transmit power at the base station and the relay for OP-SI with different power constraints. In Figure2, the total transmit power at the base station and the relay are plotted. Particularly the numbers of antennas at the relay and the base station are set as N=3and M=2, respectively, and the power of noise is fixed as −10 dBm. As shown in the figure, the differences of between the schemes using the long term and instantaneous power constraints are quite small.Back to article page
