Not Accessible

Your library or personal account may give you access

Abstract

We compare the transmission performance of various bandwidth-efficient LDPC coding schemes. Equipped with 4 dB improvement in OSNR sensitivity, we demonstrate 1 Tb/s CO-OFDM over 1600 km SSMF transmission at spectral efficiency of 3.2 bit/s/Hz.
