On Channel Inseparability and the DoF Region of MIMO Multi-way Relay Channels
Anas Chaaban, Aydin Sezgin
Full-duplex multi-way relaying is a potential solution for supporting high data rates in future Internet-of-Things (IoT) and 5G networks. Thus, in this paper the full-duplex MIMO m…
When Can a Relay Reduce End-to-End Communication Delay?
Anas Chaaban, Aydin Sezgin
The impact of relaying on the latency of communication in a relay channel is studied. Both decode-forward (DF) and amplify-forward (AF) are considered, and are compared with the po…
The Degrees-of-Freedom of Multi-way Device-to-Device Communications is Limited by 2
Anas Chaaban, Henning Maier, Aydin Sezgin
A 3-user device-to-device (D2D) communications scenario is studied where each user wants to send and receive a message from each other user. This scenario resembles a 3-way communi…
Extended Generalized DoF Optimality Regime of Treating Interference as Noise in the X Channel
Soheil Gherekhloo, Anas Chaaban, Aydin Sezgin
The simple scheme of treating interference as noise (TIN) is studied in this paper for the 3 x 2 X channel. A new sum-capacity upper bound is derived. This upper bound is transform…
Resolving Entanglements in Topological Interference Management with Alternating Connectivity
Soheil Gherekhloo, Anas Chaaban, Aydin Sezgin
The sum-capacity of a three user interference wired network for time-varying channels is considered. Due to the channel variations, it is assumed that the transmitters are only abl…
Simultaneous Diagonalization: On the DoF Region of the K-user MIMO Multi-way Relay Channel
Anas Chaaban, Karlheinz Ochs, Aydin Sezgin
The K-user MIMO Y-channel consisting of K users which want to exchange messages among each other via a common relay node is studied in this paper. A transmission strategy based on…
