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.

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 ...

Analysis of Chaos-Based Coded Modulations under Intersymbol Interference [PDF]
, 2010 Chaos-based communications systems have shown to be of potential interest in some kinds of dispersive channels. In this paper we analyze the behavior of a class of chaos-based coded modulations (CCM’s) in channels with time-invariant intersymbol ...

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 ...
