Experimental demonstration of nonbinary LDPC convolutional codes for DP-64QAM/256QAM 来自 ResearchGate 喜欢 0 阅读量: 28 作者:T Koike-Akino,K Sugihara,DS Millar,M Pajovic,P Bayvel 摘要: We show the great potential of nonbinary LDPC convolutional codes (NB-LDPC-CC) with low-latency windowed ...
摘要: We report first successful real-time self-homodyne coherent bi-direction transmission demonstration with 600-Gb/s DP-64QAM under un-cooled ~7-MHz linewidth DFB laser. A novel coherent receiver is proposed to achieve automatic stabilization against polarization fluctuations of received LO....
80-Gbaud DP-64QAM obtains the highest optical signal-to-noise ratio (OSNR) requirement and the highest bit-error rate (BER) floor but the best tolerance of chromatic dispersion (CD). 120-Gbaud DP-16QAM achieves the lowest OSNR requirement and the lowest BER floor but the worst tolerance of...

For the low-cardinality DP-QAM04 format the required security gap is mainly equal to the theoretically achievable minimum security gap. However, with increasing cardinality of the modulation format, the practical implementation penalty accounts for a significant portion of the security gap of up to ...
Experimental Investigation of Security Gaps when using Punctured LDPC Coding in Coherent Systems up to 64-GBd DP-64QAMIn optical transmission systems, security against eavesdroppers is of increasing importance. Following the concept of physical-layer security, we experimentally quantify the security gap ...
