Downlink CCM Estimation via Representation Learning with Graph Regularization

Autor: Zerin, Melih Can, Vural, Elif, Yılmaz, Ali Özgür

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 (MIMO) communication systems with base station (BS) possessing a uniform

Quasi-Newton FDE in One-Bit Pseudo-Randomly Quantized Massive MIMO-OFDM Systems

Autor: Yılmaz, Gökhan, Yılmaz, Ali Özgür

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-bit uplink multi-user massive multiple-input multiple-output (MIMO) syst

Pseudo-Random Quantization Based Two-Stage Detection in One-Bit Massive MIMO Systems

Autor: Yılmaz, Gökhan, Yılmaz, Ali Özgür

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. The performance gap between the low and high-resolution systems is sma
