Rate-Adaptive Coded Modulation with Geometrically-shaped Constellations

Not Accessible

Your library or personal account may give you access

Abstract

Information-theoretic metrics are used to design rate-adaptive coded modulation based on geometrically-shaped constellations with soft- and hard-decision FEC. Numerical results show that an 8% reach extension can be achieved with flexible data rates and transmission distances.
