Fig. 6From: MSE minimized joint transmission in coordinated multipoint systems with sparse feedback and constrained backhaul requirementsPerformance of the adopted ZF, adopted Wiener and the proposed precoders in terms of MSE in SFB-CBH configuration with \(r_{fl}=r_{bl}=0.33,\ {\mathrm{N}}_{t}=1\). The channel is time-variant with \(\triangle t=1\ {\mathrm{ms}}\) and \(v=5\ {\mathrm{km/h}}\)Back to article page
