Compressive Cascaded Channel Covariance Sensing for UPA-Type RIS-Aided Dual-Wideband Systems Ozen, Hakan; Güvensen, Gökhan Muzaffer (2025-01-01) This letter introduces a novel cascaded channel covariance matrix (C-CCM) estimation method for millimeter wave (mmWave) uniform planar array (UPA)-type reconfigurable intelligent surface (RIS)-aided dual-wideband multiple...
Subspace Aware Compressive Sensing Aided Detection for MIMO OFDM based ISAC MIMO OFDM Tabanli ISAC i in Alt Uzay Farkinda Siki stirmali Algilama Destekli Tespit Kirdar, Baran; Güvensen, Gökhan Muzaffer (2025-01-01) In wireless communication systems, the temporal and spatial variations of the channel can significantly affect signal detection accuracy. Angular spread and Doppler effects further complicate the channel estimation process...
A Reduced Complexity Generic NOMA MAP Receiver for Wideband MIMO Channels Satana, Hasan A.; Güvensen, Gökhan Muzaffer (2024-01-01) Multiple input and multiple output (MIMO) technology and non-orthogonal multiple access (NOMA) are crucial methods for future wireless systems as they provide many advantages over conventional systems. Power domain NOMA me...
Power Angular Spectrum and Spatial Covariance Estimation for Wideband mmWave RIS Channels Ozen, Hakan; Güvensen, Gökhan Muzaffer (2024-01-01) In this study, we propose a method for estimating cascaded channel covariance matrices (C-CCMs) for millimeterwave (mmWave) reconfigurable intelligent surface (RIS)-aided massive multiple-input multiple-output (MIMO) syste...
Sensing and Mitigation of Far-Field Self-Interference for Full-Duplex MIMO Systems Kurt, Anıl; Güvensen, Gökhan Muzaffer (2024-01-01) This paper aims to investigate the isolated effect of the far-field self-interference (SI) for full-duplex MIMO communications. It is shown that the far-field SI is effective only when the scatterers are close to the users...
Beam-Squint-Aware Channel Estimation for Dual-Wideband UPA-type RIS-Aided Massive MIMO Ozen, Hakan; Yılmaz, Osman; Güvensen, Gökhan Muzaffer (2024-01-01) This letter presents a novel beam-squint-aware (BSA) channel estimation method for uniform planar array (UPA)-type reconfigurable intelligent surface (RIS)-aided frequency- and spatial-wideband (dual-wideband) massive mult...
