Figure 3From: Average minimum transmit power to achieve SINR targets: performance comparison of various user selection algorithmsAvg. Min. Transmit Power vs. M for K = 10, K S = 4, γ = 10 dB, σ2 = 0.1. The curves show that SUS completely overlaps the exhaustive search result. Performance gap between NUS and OPT decreases for large number of transmit antennas.Back to article page
