Figure 6From: Performance of distributed beamforming for dense relay deployments in the presence of limited feedback information Expected value for the real part of the sum channel μ R . It is presented as a function of the number active array elements. Dashed lines: no CSI (∘), N = 1 (□), N = 2 (◇), and N = 3 (∇). Solid (black) line: full CSI at array elements. Simulated values are denoted by (∗). Channel amplitudes are fixed with perfect power balance.Back to article page
