Aperture averaging and BER for Gaussian beam in underwater oceanic turbulence

Gökçe, Muhsin Caner; Baykal, Yahya (Elsevier Science BV, 2018-03-01)

In an underwater wireless optical communication (UWOC) link, power fluctuations over finite-sized collecting lens are investigated for a horizontally propagating Gaussian beam wave. The power scintillation index, also known ...
Aperture averaging in strong oceanic turbulence

Gökçe, Muhsin Caner; Baykal, Yahya (Elsevier Science BV, 2018-04-15)

Receiver aperture averaging technique is employed in underwater wireless optical communication (UWOC) systems to mitigate the effects of oceanic turbulence, thus to improve the system performance. The irradiance flux ...
Application of adaptive optics on bit error rate of M-ary pulse-position-modulated oceanic optical wireless communication systems

Baykal, Yahya; Gökçe, Muhsin Caner; Ata, Yalçın (2020-07)

An adaptive optics correction arising from the sum of tilt, focus, astigmatism and coma components is applied to the bit error rate (BER) of M-ary pulse-position-modulated (PPM) oceanic optical wireless communication ...
BER evaluations for multimode beams in underwater turbulence

Altay Arpalı, Serap; Baykal, Yahya; Arpalı, Çağlar (Taylor&Francis Ltd., 2016)

In underwater optical communication links, bit error rate (BER) is an important performance criterion. For this purpose, the effects of oceanic turbulence on multimode laser beam incidences are studied and compared in terms ...
Depth dependence of oceanic turbulence optical power spectrum under any temperature and salinity concentration

Gerçekcioğlu, Hamza; Baykal, Yahya (2024-04-01)

The Oceanic Turbulence Optical Power Spectrum (OTOPS) with depth variations is acquired under any temperature and salinity concentration. It is supposed that specific medium is the Atlantic Ocean at high latitude and the ...
Laser array beam scintillation in oceanic turbulence

Baykal, Yahya; Ata, Yalçın; Gökçe, Muhsin C. (2020)

In this study, on-axis scintillation of laser array beam in oceanic turbulent medium is investigated. By using Rytov method, scintillation index variations are reported in connection with the propagation distance, rate of ...
