Abstract
In this talk, we will discuss two wireless optical communication scenarios: (1) Free Space Optic (FSO) communication through adverse weather events such as fog and (2) underwater wireless optical communication. Both communication scenarios suffer from the scattering and attenuation effects due to the presence of random scattering. We will discuss the electromagnetic model for wave propagation under these conditions based on the vector radiative transfer equation. By using the model, we can evaluate the communication performance in terms of bit-error-rate. Improvement methods will also be discussed including equalization using minimum mean square error and channel estimation techniques.
