Figure 4From: Average minimum transmit power to achieve SINR targets: performance comparison of various user selection algorithmsAvg. Min. Transmit Power vs. Nb. of Users for M = 5, K S = 4, γ = 10 dB, σ2 = 0.1. SUS Simulation curve overlaps the OPT exhaustive curve but NUS-Simulation shows more performance degradation with increasing number of users.Back to article page
