Sparse Channel Estimation and Equalization for OFDM-Based Underwater Cooperative Systemsw with Amplify-and-Forward Relaying
Panayırcı, Erdal; Şenol, Habib; Uysal, Murat; Poor, H. Vincent (IEEE-INST Electrical Electronics Engineers Inc, 2016)This paper is concerned with a challenging problem of channel estimation and equalization for amplify-and-forward cooperative relay based orthogonal frequency division multi-plexing (OFDM) systems in sparse underwater ... -
Sparse Channel Estimation for OFDM-Based Underwater Acoustic Systems in Rician Fading With a New OMP-MAP Algorithm
Panayırcı, Erdal; Altabbaa, Mhd Tahssin; Uysal, Murat; Poor, H. Vincent (IEEE, 2019)In this paper a new channel estimation algorithm is proposed that exploits channel sparsity in the time domain for an orthogonal frequency division multiplexing (OFDM)-based underwater acoustical (UWA) communications systems ... -
Sparse Channel Estimation for Space-Time Block Coded OFDM-Based Underwater Acoustic Channels
Altabbaa, Mhd Tahssin; Öğrenci, Arif Selçuk; Panayırcı, Erdal; Poor, H. Vincent (Institute of Electrical and Electronics Engineers Inc., 2018)Communication over acoustic signals underwater results in multi-scale multi-lag channels due to multipath propagation. Hence a robust channel estimation technique has to be present at the receiver. In this paper assuming ... -
Spatial Constellation Design Based Generalized Space Shift Keying for Physical Layer Security of Multi-User MIMO Communication Systems
Su, Nugman; Panayırcı, Erdal; Koca, Mutlu; Poor, H. Vincent (Institute of Electrical and Electronics Engineers Inc., 2021)We propose a novel spatial constellation design (SCD) method with generalized space shift keying (GSSK-SCD) signaling for physical layer security (PLS) in multi-user (MU) multiple-input multiple-output (MIMO) communication ... -
Spatial Modulation Aided Physical Layer Security for NOMA-VLC Systems
Panayırcı, Erdal; Koca, Mutlu; Haas, Harald; Poor, H. Vincent (IEEE-Inst Electrical Electronics Engineers Inc, 2023)We consider the physical layer security (PLS) problem in multi-user non-orthogonal multiple access (NOMA) enabled multiple-input multiple-output (MIMO) visible light communication systems intercepted by a passive eavesdropper ... -

Super-orthogonal trellis-coded spatial modulation
Basar, Ertugrul; Aygölü, Ümit; Panayırcı, Erdal; Poor, H. Vincent (Inst Engineering Technology-IET, 2012)Spatial modulation (SM) which employs the indices of multiple transmit antennas to transmit information in addition to the conventional M-ary signal constellations is a novel transmission technique that has been proposed ... -
Trellis coding for spatial modulation [Uzaysal modulasyon i?çi?n kafes kodlama]
In this study by combining trellis coding with spatial modulation (SM) a new multiple-input multiple output (MIMO) communication scheme called trellis coded spatial modulation (TC-SM) is proposed. For uncorrelated Rayleigh ...
