Performance of the active CSI feedback.(a) We use two different CSI traces (real and synthetic traces). The channel coefficients of the synthetic trace follow the Rayleigh distribution explained in Section 3.1. (b) We use weights of (0.4,0.4,0.2) as the nonequal weights cases. The results for (‘neq’, ‘synthetic’) are omitted because they show a similar pattern as those for ‘real’. (a) ECG distributions. (b) Performance comparison with respect to γ.
