Fig. 13From: MSE minimized joint transmission in coordinated multipoint systems with sparse feedback and constrained backhaul requirementsMSE performance of the proposed precoder as function of edge SNR in various number of transmit antennas in SFB-CBH (\(r_{fl}=r_{bl}=0.3\)) and FFB-FBH configurations. The channel is time-variant with \(\Delta t=1\ {\mathrm{ms}}\), \(v=5\ {\mathrm{km/h}}\) and \({\mathrm{N}}_{r}=2\)Back to article page
