Figure 6From: Combined transmit beamforming and channel-aware scheduling for interference mitigation in femtocellsMax-min and min rates for outage probability 10% and 50%. Red (o): Single-antenna. Green (□): 1-bit mode 1. Blue (◇): 2-bit mode 1. Magenta (▿): ∞-bit mode 1. Solid line: TBF plus channel-aware scheduling using γ ̂ th ( c ) (all cases). Dashed line: only TBF (min outage rate). Interference scenario: γ ¯ 1 → 1 =(15−Δ) dB, γ ¯ 1 → 2 =(0−Δ) dB, γ ¯ 2 → 1 =(15−Δ) dB, and γ ¯ 2 → 2 =(20−Δ) dB. All cases: P N used as reference power. Point values (“∗”) were simulated to verify the analytical results.Back to article page
