Three-Dimensional Subcarrier-Multiplexed Nonbinary- LDPC-Coded Modulation Schemes Enabling Ultra High Speed Optical Communications
Fiber optics communications Modulation Low-density parity-check codes
2015/5/25
We propose nonbinary-LDPC-coded modulation schemes employing subcarrier-multiplexing and three-dimensional constellations. We improve coding gains of conventional PDM-M-QAM by 2.17dB and 2.92dB, for M...
