Figure 5From: Average minimum transmit power to achieve SINR targets: performance comparison of various user selection algorithmsAvg. Min. Transmit Power per User vs. Nb. of Selected Users for M = 10, K = 20, γ = 10 dB, σ2 = 0.1. The curves show that communication becomes highly power inefficient when the number of simultaneously scheduled users K s grows close to the number of BS antennas M.Back to article page
