Discrete Modulation for Interference Mitigation
IEEE Transactions on Information Theory, 2020 This paper analyzes the performance of discrete input distributions (coded modulation) in interference channels. This approach is motivated in part by the necessity of using coded modulation in practical systems, and in part by the potential of discrete ...

A Study of Discrete Multitone Modulation for Wireline Links Beyond 100 Gb/s
IEEE Open Journal of Circuits and Systems, 2021 To overcome the severe losses beyond 28 GHz in low-cost electrical channels, 4-level pulse-amplitude modulation (4-PAM) wireline links targeting 112 Gb/s incorporate resource- or power-intensive equalization schemes such as decision-feedback equalizers ...

Asymptotic Security Analysis of Discrete-Modulated Continuous-Variable Quantum Key Distribution
Physical Review X, 2019 Continuous-variable quantum key distribution (CV QKD) protocols with discrete modulation are interesting due to their experimental simplicity and their great potential for massive deployment in the quantum-secured networks, but their security analysis is

Filtered Modules over Discrete Valuation Domains
Journal of Algebra, 1998 The authors investigate the notions of a valuated module \((v\)-module) over a discrete valuation domain with prime \(p\) and the dual of a coset-valuated module \((c\)-module) in terms of filtered modules focusing on the submodules \(B(\alpha)= \{b\in B:v(b) \leq \alpha\}\) rather than on the valuations themselves.

Adaptive Modulation in Multi-user Cognitive Radio Networks over Fading Channels
, 2013 In this paper, the performance of adaptive modulation in multi-user cognitive radio networks over fading channels is analyzed. Multi-user diversity is considered for opportunistic user selection among multiple secondary users.

, 2017 In this paper, we propose a novel joint coding-modulation technique based on serial concatenation of orthogonal linear transform, such as discrete Fourier transform (DFT) or Walsh-Hadamard transform (WHT), with memoryless nonlinearity.
