Sparse Channel Estimation for Space-Time Block Coded OFDM-Based Underwater Acoustic Channels 

Altabbaa, Mhd Tahssin; Öǧrenci, Arif Selçuk; Panayırcı, Erdal; Poor, H. Vincent (IEEE, 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 ...

New Trellis Code Design for Spatial Modulation 

Basar, Ertugrul; Aygölü, Ümit; Panayirci, Erdal; Poor, H. Vincent (IEEE-INST Electrical Electronics Engineers Inc, 2011)
Spatial modulation (SM) in which multiple antennas are used to convey information besides the conventional M-ary signal constellations is a new multiple-input multiple-output (MIMO) transmission technique which has recently ...

Super-orthogonal trellis-coded spatial modulation 

Basar, Ertugrul; Aygölü, Ümit; Panayirci, 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 ...

Relay-Aided Secure Broadcasting for VLC 

Arafa, Ahmed; Panayırcı, Erdal; Poor, H. Vincent (IEEE, 2018)
A visible light communication (VLC) broadcast channel is considered in which a transmitter communicates with two receivers in the presence of an external eavesdropper. Trusted cooperative half-duplex relays are deployed ...

Sparse Channel Estimation for OFDM-Based Underwater Acoustic Systems in Rician Fading With a New OMP-MAP Algorithm 

Panayirci, 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 ...

Orthogonal Frequency Division Multiplexing With Index Modulation 

Başar, Ertuğrul; Aygölü, Ümit; Panayırcı, Erdal; Poor, H. Vincent (IEEE-INST Electrical Electronics Engineers Inc, 2013)
In this paper a novel orthogonal frequency division multiplexing (OFDM) scheme called OFDM with index modulation (OFDM-IM) is proposed for operation over frequency-selective and rapidly time-varying fading channels. In ...

Performance of spatial modulation in the presence of channel estimation errors 

Basar, Ertuğrul; Aygölü, Ümit; Panayırcı, Erdal; Poor, H. Vincent (IEEE-INST Electrical Electronics Engineers Inc, 2012)
This work investigates the negative effects of channel estimation errors on the performance of spatial modulation (SM) when operating over flat Rayleigh fading channels. The pairwise error probability of the SM scheme is ...
