Problem statement

Determine the exact capacity region of the memoryless real two-user Gaussian interference channel Y1=X1+aX2+Z1Y_1=X_1+aX_2+Z_1 and Y2=bX1+X2+Z2Y_2=bX_1+X_2+Z_2 for arbitrary fixed a,b∈Ra,b\in\mathbb R, independent standard Gaussian noises, and average power constraints E[Xi2]≤Pi\mathbb E[X_i^2]\le P_i.
