Interference Management Using Nonlinear Relaying

—We consider the three-node Gaussian relay channel where the relay observes a noisy version of the interference present in the source–destination link. We investigate three fundamental relaying approaches: linear relaying, memoryless nonlinear relaying, and compress-and-forward (CF). For interference-limited cases, we illustrate that optimized memoryless nonlinear relaying almost achieves the capacity.
