Robust End-to-End Image Transmission with Residual Learning
Cenk M. Yetis
Recently, deep learning (DL) based image transmission at the physical layer (PL) has become a rising trend due to its ability to significantly outperform conventional separation-ba…
Joint Analog Beam Selection and Digital Beamforming in Millimeter Wave Cell-Free Massive MIMO Systems
Cenk M. Yetis, Emil Björnson, Pontus Giselsson
Cell-free massive MIMO systems consist of many distributed access points with simple components that jointly serve the users. In millimeter wave bands, only a limited set of predet…
Distributed Multi-Stream Beamforming in MIMO Multi-Relay Interference Networks
Cenk M. Yetis, Ronald Y. Chang
In this paper, multi-stream transmission in interference networks aided by multiple amplify-and-forward (AF) relays in the presence of direct links is considered. The objective is…
Second-Order Statistics of MIMO Rayleigh Interference Channels: Theory, Applications, and Analysis
Ahmed O. D. Ali, Cenk M. Yetis, Murat Torlak
While first-order channel statistics, such as bit-error rate (BER) and outage probability, play an important role in the design of wireless communication systems, they provide info…
Balancing Weighted Substreams in MIMO Interference Channels
Cenk M. Yetis, Yong Zeng, Kushal Anand +2
Substreams refer to the streams of each user in a system. Substream weighting, where the weights determine the prioritization order, can be important in multiple-input multiple-out…
Sub-Stream Fairness and Numerical Correctness in MIMO Interference Channels
Cenk M. Yetis, Yong Zeng, Kushal Anand +2
Stream fairness, fairness between all streams in the system, is a more restrictive condition than sub-stream fairness, fairness between all streams of each user. Thus sub-stream fa…
Sub-Stream Fairness and Numerical Correctness in MIMO Interference Channels
Cenk M. Yetis, Yong Zeng, Kushal Anand +2
Signal-to-interference plus noise ratio (SINR) and rate fairness in a system are substantial quality-of-service (QoS) metrics. The acclaimed SINR maximization (max-SINR) algorithm…
Improving Achievable Rate for the Two-User SISO Interference Channel with Improper Gaussian Signaling
Yong Zeng, Cenk M. Yetis, Erry Gunawan +2
This paper studies the achievable rate region of the two-user single-input-single-output (SISO) Gaussian interference channel, when the improper Gaussian signaling is applied. Unde…
On Feasibility of Interference Alignment in MIMO Interference Networks
Cenk M. Yetis, Tiangao Gou, Syed A. Jafar +1
We explore the feasibility of interference alignment in signal vector space -- based only on beamforming -- for K-user MIMO interference channels. Our main contribution is to relat…
Feasibility Conditions for Interference Alignment
Cenk M. Yetis, Syed A. Jafar, Ahmet H. Kayran
The degrees of freedom of MIMO interference networks with constant channel coefficients are not known in general. Determining the feasibility of a linear interference alignment sol…
A New Training Protocol for Channel State Estimation in Wireless Relay Networks
Cenk M. Yetis, Ahmet H. Kayran
The accuracy of channel state information (CSI) is critical for improving the capacity of wireless networks. In this paper, we introduce a training protocol for wireless relay netw…
