... analysis on the joint impact of the optimum distortion exponent and the optimum distortion factorexplains the behavior of the optimum expected end -to- end distortion varying with the numbers of antennas, ... Therefore, when Nmin≤ 5, ED∗uncisdecreasing because Δ∗uncis increasing; although the optimumdistortion factor μ∗uncis increasing, the increase of Δ∗uncdominates the tendency of ... whenNminstops increasing, though the number of antennas onone side is increasing. In Figure 3(b),intermsofTheorem 3,μ∗unc, represented by the dot-dash lines, is monotonicallydecreasing with...
