Effect of strong atmospheric non-Kolmogorov turbulence on the M-ary PSK subcarrier intensity modulated free space optical communications system performance

Gökçe, Muhsin Caner; Ata, Yalçın; Baykal, Yahya (Optical Soc Amer, 2019-05-01)

Atmospheric turbulence is one of the significant phenomena that degrades the free space optical (FSO) communications system performance, and thus designers need to define the requirements related to turbulence and optimize ...
M-ary pulse position modulation performance in strong atmospheric turbulence

Gökçe, Muhsin Caner; Baykal, Yahya; Ata, Yalçın (Optical Soc Amer, 2018-12-01)

The performance of an M-ary pulse position modulated (PPM) optical wireless communication system operating in strong atmospheric turbulence is investigated. Bit error rate (BER) is employed as the measure for the performance. ...
Off-axis average transmittance and beam spread of a partially coherent flat-topped beam in a turbulent underwater medium

Keskin, Aysan; Baykal, Yahya (Optical Soc Amer, 2019-08-01)

The effects of oceanic turbulence on the off-axis optical transmittance and beam spread are examined when a partially coherent flat-topped beam wave propagates in an underwater medium. To observe the oceanic turbulence ...
