Duobinary-Coded Coherent ΣΔ Radio-over-Fiber Transmission at 9 GHz Downlink Channel Spacing

Bernhard Schrenk and Florian Honz

Not Accessible

Your library or personal account may give you access

Abstract

We show digitized radio-over-fiber transmission using coherent envelope detection. A low EVM of 1.3%, a high optical budget of 34.6dB and 25% improvement in spectral occupancy are found when introducing duobinary signaling and coherent detection.
