A Superimposed Relaying Strategy and Power Allocation for Outdoor Visible Light Communications

Abstract

In this paper, we consider an outdoor visible light communications relaying system in which the relay node needs to transmit both its own information and the information from a source node simultaneously. A superimposed relaying (SR) strategy and the corresponding constellation design are presented. We derive the closed-form dominant term of average bit… (More)
