Multiplexing technique of radio-on-fiber signals on a single optical carrier using chromatic dispersion control

This paper presents a novel multiplexing technique of wireless signals of the same frequency band, such as multiple-input-multiple-output (MIMO) signal, on a single optical carrier. In proposed multiplexing technique the use of chromatic dispersion controllers is a key to the suppression of signal interferences. In general RoF system, received wireless signal intensity is periodically varied depending on chromatic dispersion that is known as fading problem. In proposed technique null points of this fading are intentionally applied to minimize signal interference. De-multiplexing two radio signals of 10GHz-band with data of 30Mbps 64QAM is experimentally demonstrated.
