Abstract

When an optical signal propagates from ground to satellite, various effects of atmosphere, viz., absorption, scattering, and turbulence, will degrade the link performance. The loss arising due to beam propagation in space and effects of atmospheric turbulence are considered in link feasibility study. In this chapter, the received optical signal power in the presence of various losses and background noise are evaluated for a given BER in weak atmospheric turbulence. Subsequently, link power budget is made and the link power margin is determined. Improvement in the link margin has been worked out with transmit diversity and coding scheme when used separately.
