Impact of Non-Ideal Pulse Carving Induced Phase Distortions on QPSK based Modulation Format
Non-Ideal Pulse Induced Phase Distortions QPSK Modulation Format
2015/7/17
We investigate impact of non-ideal pulse carver induced phase distortions on QPSK format. The results show that only 0.5 dB amplitude imbalance of sinusoidal wave applied into carver produces 2 dB ONS...
Symbol Rate Dependency of XPM-induced Phase Noise Penalty on QPSK-based Modulation Formats
Symbol Rate Dependency XPM-induced Phase QPSK-based Modulation
2015/7/31
Systematic investigation of XPM impact on QPSK signals reveals that higher symbol rates are advantageous for reducing both intra-span generation and multi-span accumulation of phase noise.
