Low complexity nonlinear detection for multiuser hybrid MIMO systems and performance analysis Salman, Murat Babek; Güvensen, Gökhan Muzaffer; Çiloğlu, Tolga (2023-10-01) This paper proposes an analytical framework and a system of distortion-aware receiver structures for single-carrier uplink hybrid beamforming-based multiple-input-multiple-output (MIMO) channels. Proposed single-user proce...
Analytical Nonlinear Distortion Characterization for Frequency-Selective Massive MIMO Channels Salman, Murat Babek; Björnson, Emil; Güvensen, Gökhan Muzaffer; Çiloğlu, Tolga (2023-01-01) Nonlinear distortion stemming from low-cost power amplifiers may severely affect wireless communication performance through out-of-band (OOB) radiation and in-band distortion. The distortion is correlated between different...
An Adaptive-Iterative Nonlinear Interference Cancellation in Time-Varying Full-Duplex Channels Kurt, Anıl; Salman, Murat Babek; Saraç, Uğur Berkay; Güvensen, Gökhan Muzaffer (2022-01-01) In this paper, first, the sensitivity of traditional Full-Duplex (FD) communication systems to time variation in the self-interference (SI) channel is demonstrated via performance analysis. It is seen that conventional sch...
An Efficient QAM Detector via Nonlinear Post-Distortion Based on FDE Bank Under PA Impairments Salman, Murat Babek; Güvensen, Gökhan Muzaffer (2021-10-01) In this paper, we propose a receiver structure for single-carrier uplink transmission with frequency domain equalization (FDE) that is exposed to power amplifier (PA) nonlinearities. A two-stage approach is adopted, in whi...
A Nonlinear Detector for Uplink SC-FDE mm-Wave Hybrid Massive MIMO under Hardware Impairments Salman, Murat Babek; Güvensen, Gökhan Muzaffer (2021-06-01) In this paper, we propose a detector structure for fully connected hybrid massive MIMO systems with transceiver impairments at user equipments. In literature, memoryless compensation of nonlinear effects at the receiver si...
An Efficient Iterative SIC for Full-Duplex SC-FDE Radio under Hardware Impairments Kurt, Anıl; Salman, Murat Babek; Güvensen, Gökhan Muzaffer (2021-06-01) In this study, a novel iterative turbo digital self interference cancellation (DSIC) algorithm is proposed to eliminate remaining self interference (SI) signal, which is contaminated by signal of interest (SoI), subject to...
On the Effects of PA Nonlinearities for Hybrid Beamforming Based Wideband Massive MIMO Systems Salman, Murat Babek; Güvensen, Gökhan Muzaffer (2020-06-01) © 2020 IEEE.In this paper, we present a general framework for the investigation of the effects of power amplifier (PA) non-linearities on the hybrid beamforming based massive multiple-input multiple-output (MIMO) systems. ...
Investigation of Effects of PA Non-linearities on the Fully Digital Massive MIMO Systems Salman, Murat Babek; Güvensen, Gökhan Muzaffer; Çiloğlu, Tolga (2020-01-01) In this study, effects of power amplifier (PA) non-linearities on the performance of fully digital massive MIMO systems are studied. Fully digital systems have been studied extensively in the literature. However, research ...
Gradient controlled improved proportionate affine projection sign algorithm Gradyan kontrollü geliştirilmiş orantili afin izdüşümlü işaret algoritmasi Salman, Murat Babek; Çiloğlu, Tolga (2018-07-05) Recently, proportionate adaptive filters are commonly used in the acoustic echo cancellation problems. In proportionate adaptive filters, for each coefficient a step-size which proportional to magnitude of that coefficient...
