Abstract
Radio over fiber (RoF) technique has revolutionized communication industry with its high data transmission rate and ability to carry the radio signal with speed of light. It finds its application in wireless local area networks (WLANs) due to easy of deployment and low cost. This paper utilizes alternate mark inversion (AMI) technique in wave length division multiplexing (WDM) scheme to further enhance data carrying capacity of the system. It is observed that proposed AMI-WDM scheme is better technique for providing high data rates and is confirmed via SNR, Q factor and eye diagrams.
