The Implementation of Adaptive Networks with Visible Light Communication Channels Modeled with Gamma-Gamma Turbulence

摘要

This paper considers the possibility and the details of implementing adaptive networks with visible light communication technology. Adaptive networks have various indoor and outdoor applications hence, their implementations with light waves face with different problems. Almost all free space optical (FSO)communication systems must deal with two channel deficiencies namely, optical noise and channel turbulence. Both channel noise and turbulence follow certain distributions that we explain in detail. In this paper, we analyze the effects of these disturbances on the estimation performance of incremental adaptive networks and present the results using various simulations. The results are presented by the means of mean square error values. Also, for Gaussian noise and Gamma-Gamma turbulence models we derived the theoretical mean square deviation (MSD)and excess mean square error (EMSE)values and compared them with the simulation outcomes.
