Nash equilibrium action profiles as a function of the channel ratios$\frac{{\mathit{g}}_{\mathbf{11}}}{{\mathit{g}}_{\mathbf{12}}}$and$\frac{{\mathit{g}}_{\mathbf{21}}}{{\mathit{g}}_{\mathbf{22}}}$for the two-player-two-channel game${\mathcal{G}}_{\mathbf{\left(}\mathbf{a}\mathbf{\right)}}$. The function $\psi :{ℝ}_{+}\to {ℝ}_{+}$ is defined as follows: ψ(x) = 1 + SNR x. The best response function BR _k (p_−k), for all $k\in \mathcal{K}$, is defined by (12). Here, it has been arbitrarly assumed that $\frac{\psi \left(g_{21}\right)}{\psi \left(g_{12}\right)}<\frac{\psi \left(g_{11}\right)}{\psi \left(g_{22}\right)}$.
