Fig. 4From: Low complexity channel estimation algorithm using paired spatial signatures for UAV 3D MIMO systemsNumber of MFLOPs versus number of antennas, \(L = 16\), \(G = 4\), \(N_{g} = 4\), \(N_{\rm ro} = 60\) \(N_{\rm co} = 10\), \(N_{b} = 10\). Shows the comparison of different algorithm computational complexity. Curve of the number of MFLOPs changes with the number of antennasBack to article page
