Abstract
The paper addresses the problem of distribution of high-definition video over fiber-wireless networks. The physical layer architecture with the low complexity envelope detection solution is investigated. We present both experimental studies and simulation of high quality high-definition compressed video transmission over 60 GHz fiber-wireless link. Using advanced video coding we satisfy low complexity and low delay constraints, meanwhile preserving the superb video quality after significantly extended wireless distance.
Highlights
The motivations for this work are three-fold
In this work we explore the notion of joint optimization of physical layer parameters of a RoF link and the codec parameters based on peak signal-to-noise ratio (PSNR) as an objective video quality metric
An Erbium doped fiber amplifier (EDFA) is employed to compensate the losses, and an optical band pass filter (OBPF) is used afterwards to mitigate the amplified spontaneous emission (ASE) noise produced by the EDFA
Summary
The motivations for this work are three-fold. The unprecedented frequency range around 60 GHz (from 4 to 9 GHz within 57-66 GHz) has been regulated for unlicensed use in a number of countries around the world. Second motivation is the introduction of high quality video services such as high-definition (HD) video conferencing and distributed video gaming. These services define both the demand for increased data rates in the access networks and need for optimization of video compression schemes.

Radio-over-fiber (RoF) is considered a promising example of such integration for optical networks [1]
