Towards arbitrary time-frequency mode squeezing with self-conjugated mode squeezing in fiber

open access: yesNature Communications
Optical parametric amplification generates squeezed light in device-specific sets of time-frequency eigenmodes, and it has been widely accepted that detection and utilization of squeezing must comply with this modal constraint.

Burst-by-Burst Adaptive Multiuser Detection CDMA: A Framework for Existing and Future Wireless Standards

open access: yes, 2003
This paper provides a broad overview of the multiuser detection literature of the past few years in a nonmathematical, easily accessible approach. The treatment is then extended to the comparative study of channel-quality controlled burst-by-burst (BbB ...

3D Object Detection for Self-Driving Vehicles Enhanced by Object Velocity

open access: yesIEEE Access
A large number of vision sensors has been proposed for enabling self-driving vehicles to perceive their surroundings. Among them, Light Detection And Ranging (LiDAR) presents the unique advantage of acquiring a high resolution 3D representation of the ...

Filter-Assisted Self-Coherent Detection Field Recovery Scheme for Dual-Polarization Complex-Valued Double-Sideband Signals

open access: yesPhotonics
In this paper, we have proposed a filter-assisted self-coherent detection (FASCD) scheme that reconstructs the optical field of a dual-polarization complex-valued double-sideband (DP-CV-DSB) signal.

Novel Spectrum Inversion-Based Double-Sideband Modulation with Low Complexity for a Self-Coherent Detection System

open access: yesPhotonics
In high-capacity and short-reach applications, double-sideband self-coherent detection (DSB-SCD) has garnered significant attention due to its ability to recover optical fields of DSB signals without requiring a local oscillator.

Joint interference of laser linewidth, chromatic dispersion, and multipath interference mitigation in self-coherent detection

open access: yesOptics Express
Self-coherent detection is a promising solution for extended range (ER) and ze best range (ZR) transmission in data centers due to its ability to recover the optical field with low complexity. However, in practical applications, the interaction between laser phase noise and fiber chromatic dispersion (CD) can lead to equalization-enhanced phase noise ...

Iterative amplitude/phase multiple-symbol differential sphere detection for DAPSK modulated transmissions

open access: yes, 2012
Differentially encoded and non-coherently detected transceivers exhibit a low complexity, since they dispense with complex channel estimation. Albeit this is achieved at the cost of requiring an increased transmit power, they are particularly beneficial,

Self-beliefs and bullying : unravelling the relation between bullying, being bullied and self-concept for upper elementary school aged children

open access: yes, 2006
Previous examinations of relations between bullying, victimisation, and self-concept have been flawed by erroneous research practices such as the un-attenuated use of dichotomous variables to measure relationships between continuous variables (Finger ...
