Figure 7From: Performance of distributed beamforming for dense relay deployments in the presence of limited feedback information Ergodic capacities for different numbers of phase bits. They are presented as a function of the number of active array elements when the average SNR γ ¯ =10 dB. Dashed lines represent the following theoretical curves: N = 0 (∘), N = 1 (□), N = 2 (◇), and N = 3 (▿). Solid (black) line: full CSI at RSs. Simulated values are denoted by (∗). Channel amplitudes are fixed with perfect power balance.Back to article page
