Figure 7: "?>(a) Impact of the level of cooperation and system load: system-wide MSEs for Case A (setups 1a, 2a, 3a, 4a (Non-CoMP), and 4a (CBF)) and Case B (setups 1b, 2b, 3b, 4b (Non-CoMP), and 4b (CBF)) under the per-antenna and per-transmitter power constraints. The blue solid lines, red dotted lines, black dashed lines, magenta dash-dot lines, and olive solid lines with dots represent, respectively, the results of setups 1x, 2x, 3x, 4x (Non-CoMP) and 4x (CBF) under the per-transmitter power constraint. And the blue □’s, red ’s, black +’s, magenta ’s, and olive ×’s represent the corresponding results under the per-antenna power constraint, (b) Impact of the level of cooperation and system load: System-wide BER’s for Case A (setups 1a, 2a, 3a, 4a (Non-CoMP), and 4a (CBF)) and Case B (setups 1b, 2b, 3b, 4b (Non-CoMP), and 4b (CBF)) under the per-antenna and per-transmitter power constraints.
