Power Allocation for Downlink Hybrid Power Line and Visible Light Communication System

Integrated system of white LED visible-light communication and power-line communication

Power Allocation for Relay-Assisted Indoor Power Line Communication Systems

Using the worldwide already existing power lines as a communication medium for local area networking (LAN) has received much interest for many indoor information sharing applications. However, the indoor power line communication (PLC) channels demonstrate hostile characteristics for broadband signal transmission. A lot of efforts have been made in order to apply some advanced technologies, whic...

Enabling Low-power Duplex Visible Light Communication

The new generation of LED-based illuminating infrastructures has enabled a “dual-paradigm" where LEDs are used for both illumination and communication purposes. The ubiquity of lighting makes visible light communication (VLC) well suited for communication with mobile devices and sensor nodes in indoor environment. Existing research on VLC has primarily been focused on advancing the performance ...

A Suitable Coding Scheme for Broadband Power-line Communication

This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...

Backhaul-Aware Decoupled Uplink and Downlink User Association, Subcarrier Allocation, and Power Control in FiWi HetNets

Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...
