A Literature Survey on Performance of Free-Space Optical Communication Links under Weak to Strong Turbulence

M. Shunmuga Lakshmi, P. Kannan

Abstract


Free space optical communication systems are generally employed over distances of several kilometers. In the existing method, many ideas have been proposed to analyze the performance of FSO links. The target bit error rate is not found using the existing methods. Recently, the modulation schemes using closed form moment generating function achieves the target BER. This literature survey discusses all the existing methods and their bit error rate performance under weak to strong turbulence conditions.

Keywords
