This paper focuses on evaluating the performance of two aperture averaging methods used for compensating the effects of the air turbulence in free space optical (FSO) communications. These methods are based on using a concentration lens and spherical concave mirrors (SCM). The preliminary experimental results show that the quality of the received signal in terms of the Q-factor and the scintillation...
In this paper, the effect of fog on a free space optical (FSO) communication link employing a coherent detection binary-phase-shift-keying modulation (BPSK) scheme is experimentally investigated. The experimental work is carried out in a controlled laboratory environment where fog could be generated and its impact on the FSO link investigated. The experimental data obtained is compared to the theoretical...
This paper reports experimental results for the performance of a free space optical (FSO) communication link employing a binary-phase-shift-keying subcarrier modulation (BPSK) scheme under the influence of the atmospheric scintillation. A dedicated experimental atmospheric simulation chamber has been built where the effects of weak turbulence regimes on the FSO link can be investigated. The experimental...
The paper reports experimental results for the performance of a free space optical (FSO) communication link employing different modulation schemes under the influence of the atmospheric scintillation. A dedicated experimental atmospheric simulation chamber has been developed where weak and medium turbulence can be generated and its effect on the FSO link is investigated. The experimental data obtained...
