Nonbinary LDPC-Coded Modulation for High-Speed Optical Fiber Communication Without Bandwidth Expansion

Nonbinary LDPC-Coded Modulation for High-Speed Optical Fiber Communication Without Bandwidth Expansion

We propose a scheme that can attain the same transmission bit rate as the corresponding conventional polarization-division-multiplexed (PDM) quadrature amplitude modulation (QAM) scheme while occupying lower bandwidth and, hence, achieving a higher spectral efficiency. In contrast to the conventiona...
