On the Discretized Gaussian Modulation (DGM)- Based Continuous Variable-QKD
IEEE Access, 2019 To overcome the low reconciliation efficiency problem of Gaussian modulation (GM)-based-continuous variable (CV)-quantum key distribution (QKD), in this paper, we propose to use discretized GM (DGM)-based-CV-QKD. The proposed CV-QKD scheme has complexity

On the Photon Subtraction-Based Measurement-Device-Independent CV-QKD Protocols
IEEE Access, 2019 To potentially overcome the practical security loopholes of CV-QKD protocols, in this paper, we propose to use the optimized eight-state measurement-device-independent (MDI) protocol and demonstrate that it can significantly outperform corresponding ...

Maximum likelihood based estimation of frequency and phase offset in DCT OFDM systems under non-circular transmissions: algorithms, analysis and comparisons [PDF]
, 2008 Recently, the advantages of the discrete cosine transform (DCT) based orthogonal frequency-division multiplexing (OFDM) have come to the light. We thus consider DCT- OFDM with non-circular transmission (our results cover circular transmission as well ...
