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...
