Study Of Performance And Analysis Of SDM For Free Space Optical Satellite Communication Systems

Abstract

This paper proposes an M-ary SDM based free space optical satellite communication by using lasers and analyses its system performance. The system is simulated under the different intensities of atmospheric turbulence and order of modulation to derive a correlation between bit error rate of link and power of transmission. The results show that M-ary SDM modulation order increases with an increase in turbulence intensity, performance of the SDM modulation and SDM optical links degrades. This allows for the evaluation of performance and parameters for further development of SDM optical links in satellite laser communication by providing a reference.
