Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.

QCL‐Based Cryogen‐Free THz Optical Wireless Communication Link
Laser &Photonics Reviews, Volume 19, Issue 6, March 18, 2025.A novel QCL‐based, cryogen‐free, and transportable wireless communication system is presented operating at 2.83 THz. The QCL device is mounted in a compact Stirling refrigerator, while a room‐temperature graphene‐based FET is used as a receiver, implementing a binary on‐off keying (OOK) modulation scheme with Manchester encoding.

Low-Complexity Gaussian Detection for MIMO Systems
Journal of Electrical and Computer Engineering, 2010 For single-carrier transmission over delay-spread multi-input multi-output (MIMO) channels, the computational complexity of the receiver is often considered as a bottleneck with respect to (w.r.t.) practical implementations.

Engineering Reports, Volume 7, Issue 1, January 2025.ABSTRACT Due to the long transmission distance of the constellation network represented by the low‐orbit satellite system, the satellite‐to‐ground link is subject to large path loss and limited communication performance. This paper uses multi‐satellite and multi‐beam joint transmission technology to form a virtual multiplex network with ground multi ...

Subband Array Implementations for Space-Time Adaptive Processing
EURASIP Journal on Advances in Signal Processing, 2005 Intersymbol interference (ISI) and cochannel interference (CCI) are two primary sources of signal impairment in mobile communications. In order to suppress both ISI and CCI, space-time adaptive processing (STAP) has been shown to be effective in ...
