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...
On the Reverse Concatenated Coded-Modulation for Ultra- High-Speed Optical Transport
Fiber optics optical communications Reverse concatenated FEC
2015/5/25
We propose reverse concatenated code with inner BCH code and outer LDPC code.BCH decoder is based on MAP-decoding that provides high-accuracy-reliabilities for suboptimum-LDPC-decoder, leading to perf...
Coded Multidimensional Pulse Amplitude Modulation for Ultra-high-speed Optical Transmission
Coded Multidimensional Pulse Amplitude Modulation ltra-high-speed Optical Transmission
2015/5/15
We propose a coded N-dimensional pulse-amplitude modulation (ND-PAM) suitable for ultra-high-speed serial optical transport. The polarization-multiplexed-ND-PAM significantly outperforms corresponding...
Practical design rules for ultra high-speed Dense Dispersion Management Telecommunication systems
ultra high-speed Dense Dispersion Management Telecommunication systems
2015/8/4
In this work, we establish and analyze some practical design rules for the implementation of ultra-high speed(>160-Gbit/s) telecommunication systems based on dense dispersion management.
