Design of multi user free space optical communication system for Three Dimensional SPPDD for OCDMA

چکیده
3-D W/T/P encoded signal transmitted over free space optical link under the effects of atmospheric turbulences i.e. haze, fog and clear weather. System performance is best when clear weather attenuation is considered (0.1dB/Km) and results degrades in case of Haze (4dB/Km) and worst in Fog (20dB/Km).This system analyzed at varied distance for all the three turbulences, also effect of amplifiers observed to mitigate the effects of attenuation. In all the systems discussed earlier SPPDD coding used (Single Pulse Per Plane with Direct Detection). Keywords— OCDMA, 3-D codes, Wavelength, Time, Polarization, W/T/P, SPPDD, FSO

متن کاملModified MWOOC for Spectral Efficiency Improvement in 2D OCDMA system
Classical Multi Wavelength Optical Orthogonal Code (MWOOC) constructions impose several conditions on the code parameters. These limit the Optical Code Division Multiple Access (OCDMA) system potentialities in terms of performance and practical implementation. In this paper, a modified MWOOC construction is used to overcome these limitations. Indeed, this method permits designing 2D codes with ...
