recommendations! Published in 2017 at "Journal of Lightwave Technology"

DOI: 10.1109/jlt.2017.2669919

Abstract: We proposed coded eight-dimensional (8-D) quadrature amplitude modulation (QAM) and experimentally demonstrated in high baud-rate transmission. Both high baud rate and multilevel modulation techniques are necessary for large capacity long haul transmission without increasing the… read more here.

DOI: 10.1109/twc.2017.2732348

Abstract: In asynchronous physical-layer network coding (APNC) systems, the symbols from multiple transmitters to a common receiver may be misaligned. Knowledge of the amount of symbol misalignment, hence its estimation, is important to PNC decoding. This… read more here.
