Figure 2From: Average minimum transmit power to achieve SINR targets: performance comparison of various user selection algorithmsAvg. Min. Transmit Power vs. Nb. of Users for M = 4, K S = 2, γ = 10 dB, σ2 = 0.1. The curves show that SUS completely overlaps the optimal curve. NUS shows performance degradation as the number of users increases.Back to article page
