Joint MMSE Transceiver Designs and Performance Benchmark for CoMP Transmission and Reception

Figure 8

Impact of the size of the system (number of transmitter receiver pairs): normalized MSEs and system-wide BERs of various Non-CoMP and CBF setups under the per-antenna and per-transmitter power constraints. The olive solid lines with dots, red dotted lines, black dashed lines correspond to, respectively, setups 4b (CBF), 5a (CBF) and 5b (CBF) under the per-transmitter power constraint. The olive ×’s, red ◊’s, black +’s correspond to, respectively, setups 4b (CBF), 5a (CBF) and 5b (CBF) under the per-antenna power constraint. The magenta dash-dot lines and the green ○’s correspond to, respectively, setups 4b (Non-CoMP) and 5a (Non-CoMP) under the per-transmitter power constraint. The magenta ▵’s correspond to setup 4b (Non-CoMP) under the per-antenna power constraint.
