Interference management in optical attocells networks by using fractional frequency reuse

Abstract

Light fidelity (Li-Fi) is new technology using lights (LEDs) as transceiver to send and receive data. However, when Light fidelity access points (attocells) placing near to each other in the network, they interfere each other with phenomena called co-channel interference which decreasing quality of the signal. In this thesis, fractional frequency reuse introduced as solution to solve this problem. MATLAB simulator showing the impact of fractional frequency reuse to solve problem.
