On the Performance of Optical Wireless Cooperative Systems over the DGG Fading Channel

There is a growing research interests in hybrid optical and microwave wireless communications, which could be adpted in the next generation wireless networks. In this paper, based on the decode-and-forwardrelaying protocol and statistical behavior of the overall link’s signal-to-noise-ratio, we consider five different practical scenarios by dering closed-form expressions for the outage and the bit error probabilities. Using Monte Carlo simulation we verify the predicted results. It is demonstrated that, decreasing the semi-angle of LED or increasing the filed of view of VLC receiver enhance the performance.
