Anisotropy effect on performance of subcarrier intensity modulated binary phase shift keying optical wireless communication links in weakly turbulent underwater channel

Baykal, Yahya; Gökçe, Muhsin Caner; Ata, Yalçın (Taylor&Francis LTD, 2019-10)

The effect of the anisotropy on the bit-error-rate (BER) performance of subcarrier intensity modulated (SIM) binary phase shift keying (BPSK) optical wireless communication (OWC) links operating in weakly turbulent underwater ...
Ber anaylsis for super lorentz-gaussian laser beamspropagating in turbulent media

Gökçe, Muhsin Caner; Sarı, Filiz; Özek, Faruk (Gazi Univ, Fac Engineering Architecture, 2013-12)

In this work, BER-SNR variation of super Lorentz-Gaussian laser beam that propagating horizontally path in turbulent media is analyzed. Using scintillation index which is obtained by extented Huygens-Fresnel principle, BER ...
Coupling efficiency of multimode beam to fiber in atmospheric turbulence

Gökçe, Muhsin Caner; Baykal, Yahya; Ata, Yalçın (2023-07)

Atmospheric turbulence causes wavefront distortions in the propagated laser beam. By the beam shaping of the transmitted laser, wavefront distortions can be mitigated effectively. In this paper, we consider a shaped laser ...
Effect of anisotropy on bit error rate for an asymmetrical Gaussian beam in a turbulent ocean

Yalçın, Ata; Baykal, Yahya (Optical Soc Amer, 2018-03-20)

Effect of anisotropy on the average bit error rate (BER) is investigated when an asymmetrical Gaussian beam is propagated in an anisotropic turbulent ocean. BER is found to decrease in response to an increase in anisotropy ...
Effect of anisotropy on performance of M-ary phase shift keying subcarrier intensity-modulated optical wireless communication links operating in strong oceanic turbulence

Gökçe, Muhsin Caner; Baykal, Yahya; Ata, Yalçın (2020-05)

In strong oceanic turbulence, the performance of M-ary phase shift keying subcarrier intensity-modulated optical wireless communication (OWC) links is investigated in terms of the bit-error-rate (BER) by considering the ...
Error performance of optical wireless communication systems exercising BPSK subcarrier intensity modulation in non-Kolmogorov turbulent atmosphere

Ata, Yalçın; Baykal, Yahya; Gökçe, Muhsin Caner (Elsevier Science BV, 2019-04-01)

Subcarrier intensity modulation (SIM) scheme is preferred due to efficient bandwidth usage superiority over other modulation techniques such as on-off keying (OOK), pulse position modulation (PPM). In this paper, we ...
Performance analysis of M-ary pulse position modulation in strong oceanic turbulence

Gökçe, Muhsin Caner; Baykal, Yahya; Ata, Yalçın (Elsevier Science Bv, 2018-11-15)

In this paper, we consider an underwater wireless optical communication (UWOC) system which consists of an M-ary pulse position modulated (PPM) Gaussian optical beam at the transmitter and an avalanche photodiode (APD) at ...
Signal-to-noise ratio with adaptive optics compensation in non-Kolmogorov weak turbulent atmosphere

Ata, Yalçın; Baykal, Yahya; Gökçe, Muhsin Caner (2021)

This study investigates the average signal-to-noise ratio (Formula presented.) at the shot-noise limited receiver of an optical wireless communication system (OWC) that uses collimated Gaussian beam with adaptive optics ...
Simulation of free space optical links under different atmospheric conditions

Öztürk, Korhan (2011-08-28)

This thesis contains a feasibility study for the free space optical links, which would be installed in Turkey. In first chapters, some basic information and the background theory of the atmospheric channel are given. ...
Statistical properties of a radially polarized twisted Gaussian Schell-model beam in an underwater turbulent medium

Peng, Xiaofeng; Liu, Lin; Cai, Yangjian; Baykal, Yahya (Optical Soc Amer, 2017-01-01)

Average intensity and the normalized powers of the completely polarized and the completely unpolarized portions of a radially polarized twisted Gaussian Schell-model (TGSM) beam propagating in underwater turbulence are ...
Türbülanslı ortamda yayılan super Lorentz-Gauss laser demetleri için ber analizi

Gökçe, Muhsin Caner; Sarı, Filiz; Özek, Faruk (Gazi Univ, Fac Engineering Architecture, 2013-12)

Çalışmada, türbülanslı ortamda yayılan super Lorentz-Gauss laser demetlerinin yatay iletim uzaklıklarındaki BER - SNR değişimi hesaplandı. BER hesaplamalarında kullanılan pırıldama indisleri, genişletilmiş HuygensFresnel ...
