Double-Directional V2V Channel Measurement using ReRoMA at 60 GHz
Hussein Hammoud, Yuning Zhang, Zihang Cheng +9
The coordination of vehicles is a crucial element of autonomous driving, as it enhances the efficiency, convenience, and safety of road traffic. In order to fully exploit the capab…
Channel Estimation for mmWave MIMO using sub-6 GHz Out-of-Band Information
Faruk Pasic, Markus Hofer, Mariam Mussbah +4
Future wireless multiple-input multiple-output (MIMO) communication systems will employ sub-6 GHz and millimeter wave (mmWave) frequency bands working cooperatively. Establishing a…
Low-Complexity Equalization for Orthogonal Time and Frequency Signaling (OTFS)
Thomas Zemen, Markus Hofer, David Loeschenbrand
Recently, a new precoding technique called orthogonal time-frequency signaling (OTFS) has been proposed for time- and frequency-selective communication channels. OTFS precodes a da…
Iterative Detection for Orthogonal Precoding in Doubly Selective Channels
Thomas Zemen, Markus Hofer, David Loeschenbrand +1
Ultra-reliable wireless communication links require the utilization of all diversity sources of a wireless communication channel. Hadani et al. propose a two dimensional discrete s…
A time-variant channel prediction and feedback framework for interference alignment
Zhinan Xu, Markus Hofer, Thomas Zemen
In interference channels, channel state information (CSI) can be exploited to reduce the interference signal dimensions and thus achieve the optimal capacity scaling, i.e. degrees…
Tracking of Wideband Multipath Components in a Vehicular Communication Scenario
Kim Mahler, Wilhelm Keusgen, Fredrik Tufvesson +2
A detailed understanding of the dynamic processes of vehicular radio channels is crucial for its realistic modeling. In this paper, we present multipath components (MPCs) tracking…
On the Degrees of Freedom for Opportunistic Interference Alignment with 1-Bit Feedback: The 3 Cell Case
Zhinan Xu, Mingming Gan, Thomas Zemen
Opportunistic interference alignment (OIA) exploits channel randomness and multiuser diversity by user selection. For OIA the transmitter needs channel state information (CSI), whi…
Energy Management Policies for Energy-Neutral Source-Channel Coding
Paolo Castiglione, Osvaldo Simeone, Elza Erkip +1
In cyber-physical systems where sensors measure the temporal evolution of a given phenomenon of interest and radio communication takes place over short distances, the energy spent…
Asymptotic Capacity Results for Non-Stationary Time-Variant Channels Using Subspace Projections
Thomas Zemen, Stefan M. Moser
In this paper we deal with a single-antenna discrete-time flat-fading channel. The fading process is assumed to be stationary for the duration of a single data block. From block to…
