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…

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…
