“…Moreover, the front phase of the beam may varies and resulting intensity signal fluctuation. Taking account all these effect will result spatial and temporal random changes in refractive index of several elements such as temperature, pressure and wind along the optical propagation path [2][3][4][5][6][7][8][9].…”

Abstract. Diffusers transmitter modulation to reduce the effect of atmospheric turbulence in free space optical communication system is described in this paper. This technique uses dual transmitters and dual receivers which are using differential mode for detection. The combination of these components produce superior modulation method especially to reduce scintillation index, to overcome signal detection with fix zero threshold and improve power received. In order to improve the performance of free space optical system, these three elements play an important role. The analysis result show that for receiving power dual diffuser modulation at 3 km distance propagation is 4.59dBm compared to conventional OOK using diffuser which only -7.6dBm and equivalent to 3dBm improvement or up to 40 percent better.

Abstract. This paper focus on mitigating the atmospheric turbulence effect in free space optical communication using a dual diffuser modulation (DDM) technique.The most deteriorate the FSOC is scintillation where it affected the wave front cause to fluctuating signal and ultimately receiver can turn into saturate or loss signal. DD approach enhances the detecting bit '1' and bit '0' and improves the power received to combat with turbulence effect. The performance focus on Signal-toNoise (SNR) and Bit Error Rate (BER) by using the Kolmogorov's scintillation theory. The numerical result shows that the DD approach improves the range where estimated approximately 40% improvement under weak turbulence and 80% under strong turbulence.

Institution of Engineering and Technology (IET)Pernice Abstract:In this paper, we present the measurements performed on a free space optics (FSO) communications link using an indoor atmospheric chamber. In particular, we have generated several different optical turbulence conditions, demonstrating how even the weak turbulence regime can strongly affect the FSO link performance. We have carried out an in-depth analysis of the data collected during the measurements, and calculated the turbulence strength (i.e. scintillation index and Rytov variance) and the important performance metrics (i.e., the Q-factor and bit error rate) to evaluate the FSO link quality.Moreover, we have tested, for the first time, an appositely developed temporally-correlated Gamma-Gamma channel model to generate the temporal irradiance fluctuations observed at the receiver. This has been accomplished by using a complete analysis tool that enables us to fully simulate the experimental FSO link. Finally, we compare the generated time-series with the collected experimental data, showing a good agreement and thus proving the effectiveness of our model.
