We demonstrate a novel fiber nonlinearity post-equalization algorithm using principal component analysis and neural networks. We achieve ∼0.46 dBQ improvement for 21 Gbaud DP-8QAM transmission over ∼13,000 km deployed fiber with over 90% complexi

Balance between spatial capacity and diversity in a multi-core fiber system adopting maximal-ratio combining receiver is studied. Compared to standard single-mode fiber, the bit-error rate is improved when partially sharing multi-core fiber cores amo

We propose a novel technique that we call reduced complexity interleaved multi-carrier CDMA (RC I-MC-CDMA) as an alternative to MC-CDMA for indoor VLC systems. It uses shorter CDMA codes and interleaved sub-bands to lower the overall complexity witho

In this paper, Hybrid PSK-MPPM is proposed to improve the system performance of the conventional ACO-OFDM by modulating the subcarriers with less number of high power PSK modulated symbols while their positions will also be utilized to carry addition
