Wideband analysis of indoor MIMO channels [PDF]
, 2002 The application of MIMO communication systems in real environments will invariably require systems to operate over wideband channels. Although suitable techniques for processing wideband MIMO channels have been reported, their evaluation has mainly been ...

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects
Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Wind Energy, Volume 29, Issue 10, October 2026.ABSTRACT For a newly emerging kind of cascade dual‐rotor wind turbine (CDR‐WT), the coordinated control of its front and rear rotor faces significant challenges. To solve this problem, a novel modeling and control design approach is presented in this paper.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract A spectrally resolved observational methodology is introduced to estimate mesoscale momentum flux frequency spectra in the mesosphere and lower thermosphere (MLT). The method is applied to four‐dimensional wind fields reconstructed with the physics‐informed neural network approach called the Hydrodynamic Point‐wise Environment Reconstructor ...

Semi-blind joint maximum likelihood channel estimation and data detection for MIMO systems
, 2008 Semi-blind joint maximum likelihood (ML) channel estimation and data detection is proposed for multiple-input multiple-output (MIMO) systems. The joint ML optimization over channel and data is decomposed into an iterative two-level optimization loop.

Design of Large‐Aperture Hybrid Refractive Metalens System
Nanophotonics, Volume 15, Issue 18, 25 September 2026.An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...
