Two-User SIMO Interference Channel with TIN: Improper Signaling versus Time-Sharing
Christoph Hellings, Ferhad Askerbeyli, Wolfgang Utschick
In the two-user Gaussian interference channel with Gaussian inputs and treating interference as noise (TIN), improper complex signals can be beneficial if time-sharing is not allow…
Maximizing the Partial Decode-and-Forward Rate in the Gaussian MIMO Relay Channel
Christoph Hellings, Patrick Gest, Thomas Wiegart +1
It is known that circularly symmetric Gaussian signals are the optimal input signals for the partial decode-and-forward (PDF) coding scheme in the Gaussian multiple-input multiple-…
Mixed Monotonic Programming for Fast Global Optimization
Bho Matthiesen, Christoph Hellings, Eduard A. Jorswieck +1
While globally optimal solutions to many convex programs can be computed efficiently in polynomial time, this is, in general, not possible for nonconvex optimization problems. Ther…
Improper Signaling versus Time-Sharing in the Two-User Gaussian Interference Channel with TIN
Christoph Hellings, Wolfgang Utschick
So-called improper complex signals have been shown to be beneficial in the single-antenna two-user Gaussian interference channel under the assumptions that all input signals are Ga…
