"?>(a) Impact of path loss and system load: system-wide MSEs of 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 with 10log₁₀𝑃=5 dB.

(b) Impact of path loss and system load: System-wide BER’s of 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 with 10log₁₀𝑃=5 dB.
