Not Accessible

Your library or personal account may give you access

Abstract

Multicarrier Offset-QAM is proposed as a spectrally efficient scheme for high-speed coherent optical communication systems. Low penalties are found with symbol-rate spacing in a back-to-back experiment. The scheme can be implemented with low complexity.
