Carrier-assisted differential detection [PDF]
Light: Science & Applications, 2020 AbstractTo overcome power fading induced by chromatic dispersion in optical fiber communications, optical field recovery is a promising solution for direct detection short-reach applications, such as fast-evolving data center interconnects (DCIs). To date, various direct detection schemes capable of optical field recovery have been proposed, including ...

IEEE Access, 2021 In view of reducing the complexity of signal detection in massive multiple-input multiple-output (MIMO) receivers, the use of non-coherent detection is favored over usual coherent techniques that require complex channel estimation.

IEEE Access, 2023 In this work, we consider a selective Detect-and-Forward (a symbol based decode-and-forward) (DetF) multi-relay two-way network employing differential MPSK with regularized Weighted Decision Feedback Differential Coherent (WDFDC) receivers.

Multiple-Symbol Differential Sphere Detection and Decision-Feedback Differential Detection Conceived for Differential QAM [PDF]
IEEE Transactions on Vehicular Technology, 2016 Multiple-symbol differential sphere detection (MSDSD) relies on the knowledge of channel correlation. More explicitly, for differential phase-shift keying (DPSK), the transmitted symbols' phases form a unitary matrix, which can be separated from the channel's correlation matrix by the classic multiple-symbol differential detection (MSDD), so that a ...

Detecting Violations of Differential Privacy [PDF]
Proceedings of the 2018 ACM SIGSAC Conference on Computer and Communications Security, 2018 The widespread acceptance of differential privacy has led to the publication of many sophisticated algorithms for protecting privacy. However, due to the subtle nature of this privacy definition, many such algorithms have bugs that make them violate their claimed privacy.

Long-Block Differential Spatial Modulation
IEEE Access, 2023 Spatial modulation (SM) can transmit additional data bits by selecting antennas and avoids synchronization and interferences among antennas. Differential SM (DSM) is a noncoherent technique of SM, but it is less bandwidth efficient than SM.
