On the Gaussian Multiple Access Wiretap Channel and the Gaussian Wiretap Channel with a Helper: Achievable Schemes and Upper Bounds
Rick Fritschek, Gerhard Wunder
We study deterministic approximations of the Gaussian two-user multiple access wiretap channel (G-MAC-WT) and the Gaussian wiretap channel with a helper (G-WT-H). These approximati…
On Multiuser Gain and the Constant-Gap Sum Capacity of the Gaussian Interfering Multiple Access Channel
Rick Fritschek, Gerhard Wunder
Recent investigations have shown sum capacity results within a constant bit-gap for several channel models, e.g. the two-user Gaussian interference channel (G-IC), k-user G-IC or t…
On-The-Fly Secure Key Generation with Deterministic Models
Rick Fritschek, Gerhard Wunder
It is well-known that wireless channel reciprocity together with fading can be exploited to generate a common secret key between two legitimate communication partners. This can be…
On the Deterministic Sum-Capacity of the Multiple Access Wiretap Channel
Rick Fritschek, Gerhard Wunder
We study a deterministic approximation of the two-user multiple access wiretap channel. This approximation enables results beyond the recently shown secure degrees o…
