MSE and BER as functions of 10log₁₀𝑡𝑃 under per-antenna and per-cell power constraints. System parameters are shown in examples 1 and 2 in Table 1. (Legends: Solid square lines: the DCOA with (𝑚₁,𝑚₂)=(2,2); Dotted diamond lines: the GIA (FIA) with (𝑚₁,𝑚₂)=(2,2); Dash “+” lines: the GIA with (𝑚₁,𝑚₂)=(1,1).)
