Fig. 7From: Multi-user hybrid precoding for mmWave massive MIMO systems with sub-connected structureSum rate comparison for hybrid precoding schemes versus \({N_s}\). The dotted line indicates sum rate when the number of data streams per user is \({N_s} = 2\). The solid line expresses sum rate when the number of data streams per user is \({N_s} = 4\)Back to article page
