New Instances of Quadratic APN Functions
Christof Beierle, Gregor Leander
In a recent work, Beierle, Brinkmann and Leander presented a recursive tree search for finding APN permutations with linear self-equivalences in small dimensions. In this paper, we…
Robust Transceiver Design for Full-Duplex Decode-and-Forward Relay-Assisted MIMO Systems
Hossein Esmaeili, Ali Kariminezhad, Aydin Sezgin
Robust transceiver design against unresolvable system uncertainties is of crucial importance for reliable communication. For instance, full-duplex communication suffers from such u…
Spatio-Temporal Waveform Design in Active Sensing Systems with Multilayer Targets
Ali Kariminezhad, Aydin Sezgin
In this paper, we study the optimal spatio-temporal waveform design for active sensing applications. For this purpose a multi-antenna radar is exploited. The targets in the radar v…
Hybrid Beamforming: Where Should the Analog Power Amplifiers be Placed?
Yasemin Karacora, Ali Kariminezhad, Aydin Sezgin
In this paper we study the spectral efficiency (SE) of a point-to-point massive multiple-input multiple-output system (P2P-massive MIMO) with limited radio frequency (RF) chains, i…
The Generalized Degrees of Freedom of the Interference Relay Channel with Strong Interference
Soheyl Gherekhloo, Anas Chaaban, Aydin Sezgin
The interference relay channel (IRC) under strong interference is considered. A high-signal-to-noise ratio (SNR) generalized degrees of freedom (GDoF) characterization of the capac…
A Systematic Approach for Interference Alignment in CSIT-less Relay-Aided X-Networks
Daniel Frank, Karlheinz Ochs, Aydin Sezgin
The degrees of freedom (DoF) of an X-network with M transmit and N receive nodes utilizing interference alignment with the support of relays each equipped with antennas o…
The Degrees of Freedom of the MIMO Y-channel
Anas Chaaban, Karlheinz Ochs, Aydin Sezgin
The degrees of freedom (DoF) of the MIMO Y-channel, a multi-way communication network consisting of 3 users and a relay, are characterized for arbitrary number of antennas. The con…
The DoF of the K-user Interference Channel with a Cognitive Relay
Anas Chaaban, Aydin Sezgin
It was shown recently that the 2-user interference channel with a cognitive relay (IC-CR) has full degrees of freedom (DoF) almost surely, that is, 2 DoF. The purpose of this work…
Lattice Coding and the Generalized Degrees of Freedom of the Interference Channel with Relay
Anas Chaaban, Aydin Sezgin
The generalized degrees of freedom (GDoF) of the symmetric two-user Gaussian interference relay channel (IRC) is studied. While it is known that the relay does not increase the DoF…
Signal Space Alignment for the Gaussian Y-Channel
Anas Chaaban, Aydin Sezgin
A multi-way communication network with three nodes and a relay is considered. The three nodes in this so-called Y-channel, communicate with each other in a bi-directional manner vi…
Sub-optimality of Treating Interference as Noise in the Cellular Uplink
Anas Chaaban, Aydin Sezgin
Despite the simplicity of the scheme of treating interference as noise (TIN), it was shown to be sum-capacity optimal in the Gaussian 2-user interference channel in \cite{ShangKram…
