Since OPT (x, y) = min i OPT i (x, y), this also implies OPT (x, y) ≤ d x, y).
Moreover, ŵ i ε ( t ) is equivalent interference plus noise term, defined as ŵ i ε ( t ) = w i ( t ) + ∑ m = 1, m ≠ i N β m, opt, i ε ĥ m, opt, i + ĥ m, opt, i ε n m, opt, i + ĥ m, opt, i h ̄ m, opt, i ε + h ̄ m, opt, ĥ m, opt, i ε + ĥ m, opt, i ε h ̄ m, opt, i ε x m c m ( t ).
The decorrelated signal Ŷ j, i is given by Ŷ j, i = β j, opt, i h ̄ j, opt, i P j B ĥ j, opt, i x j + ŵ ̂ j, i, (28).
Following (28), the decorrelated signal can be obtained as Ŷ j, i ε = β j, opt, i ε h ̄ j, opt, i P j B ĥ j, opt, i x j + ŵ ̂ j, i ε, (81).
with means λ j, opt, i B = N 0 ϱ N - 1 P j B σ ̄ j, opt, i 2 and λ j, opt, i C = N 0 ϱ N - 1 P j, i C σ ̂ j, opt, i 2, respectively.
Hence, the optimal allocated bits are obtained as r i ( m opt ), i = 0, …, N − 1.
3rd) Throughput maximization phase: perform Algorithm 1 on Opt C i ( i ∈ K ).
Figure 1b and c give the intensity difference and phase difference with p-opt, i-opt, NF and the proposed method.
For N R =N T =4, M=2 MIMO system, the the curve of θ opt versus I BICM S N R,θ opt) is shown in Fig. 5. Fig. 5 θ opt vs. I BICM S N R,θ opt) for N R =N T =4, M=2 MIMO.
"Opt-out"?: I am thinking about the "opt-out" option.
"Opt-out"!: I want to choose the "opt-out" option and definitely plan to be added to the contradiction register.
