Downlink Channel Covariance Matrix Estimation via Representation Learning with Graph Regularization
Melih Can Zerin, Elif Vural, Ali Özgür Yılmaz
In this paper, we propose an algorithm for downlink (DL) channel covariance matrix (CCM) estimation for frequency division duplexing (FDD) massive multiple-input multiple-output (M…
Pseudo-Random Quantization Based Two-Stage Detection in One-Bit Massive MIMO Systems
Gökhan Yılmaz, Ali Özgür Yılmaz
Utilizing low-resolution analog-to-digital converters (ADCs) in uplink massive multiple-input multiple-output (MIMO) systems is a practical solution to decrease power consumption.…
Quasi-Newton FDE in One-Bit Pseudo-Randomly Quantized Massive MIMO-OFDM Systems
Gökhan Yılmaz, Ali Özgür Yılmaz
This letter offers a new frequency domain equalization (FDE) scheme that can work with a pseudo-random quantization (PRQ) scheme utilizing non-zero threshold quantization in one-bi…
A Theoretical Performance Bound for Joint Beamformer Design of Wireless Fronthaul and Access Links in Downlink C-RAN
Fehmi Emre Kadan, Ali Özgür Yılmaz
It is known that data rates in standard cellular networks are limited due to inter-cell interference. An effective solution of this problem is to use the multi-cell cooperation ide…
Beamformer Design with Smooth Constraint-Free Approximation in Downlink Cloud Radio Access Networks
Fehmi Emre Kadan, Ali Özgür Yılmaz
