On the Capacity of the Cognitive Interference Channel with a Common Cognitive Message
Stefano Rini, Carolin Huppert
In this paper the cognitive interference channel with a common message, a variation of the classical cognitive interference channel in which the cognitive message is decoded at bot…
Achievable Sum-Rates in Gaussian Multiple-Access Channels with MIMO-AF-Relay and Direct Links
Frederic Knabe, Omar Mohamed, Carolin Huppert
We consider a single-antenna Gaussian multiple-access channel (MAC) with a multiple-antenna amplify-and-forward (AF) relay, where, contrary to many previous works, also the direct…
The Capacity of the Semi-Deterministic Cognitive Interference Channel with a Common Cognitive Message and Approximate Capacity for the Gaussian Case
Stefano Rini, Carolin Huppert
In this paper the study of the cognitive interference channel with a common message, a variation of the classical cognitive interference channel in which the cognitive message is d…
Superiority of TDMA in a Class of Gaussian Multiple-Access Channels with a MIMO-AF-Relay
Frederic Knabe, Omar Mohamed, Carolin Huppert
We consider a Gaussian multiple-access channel (MAC) with an amplify-and-forward (AF) relay, where all nodes except the receiver have multiple antennas and the direct links between…
