Phase-Noise Compensation for Spatial-Division Multiplexed Transmission [PDF]

Optical Fiber Communication Conference, 2017
The problem of correlated phase noise in spatial-division multiplexed transmission is studied. To compensate for the phase noise, an algorithm for joint-core phase-noise estimation and symbol detection is proposed, which outperforms conventional methods.

Investigation of Fan In and Fan Out Technologies for Multi Core Fiber

Guangtongxin yanjiu, 2021
Spatial division multiplexing based on the multi-core fiber has been believed as a promising and effective way to overcome the foreseeable capacity crunch of single mode fiber transmission. Fan-in Fan-out (FIFO) technology for multi-core fiber is the key

Near-field THz imaging and spectroscopy using a multiple subwavelength aperture modulator

, 2013
We present a near-field, simultaneous multiple pixel subwavelength THz transmission imaging device based on a solid-state THz spatial modulator. Frequency-division multiplexing is used to acquire multiple pixels simultaneously.

Orbital Angular Momentum-based Space Division Multiplexing for High-capacity Underwater Optical Communications [PDF]

, 2016
To increase system capacity of underwater optical communications, we employ the spatial domain to simultaneously transmit multiple orthogonal spatial beams, each carrying an independent data channel.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Spatial and Wavelength Division Joint Multiplexing System Design for MIMO-OFDM Visible Light Communications

IEEE Access
The low-pass characteristics of front-end elements including light-emitting diodes (LEDs) and photodiodes (PDs) limit the transmission data rate of visible light communication (VLC) and Light Fidelity (LiFi) systems.

Frequency-Multiplexed bias and readout of a 16-pixel Superconducting Nanowire Single-Photon Detector Array

, 2017
We demonstrate a 16-pixel array of radio-frequency superconducting nanowire single-photon detectors with an integrated and scalable frequency-division multiplexing architecture, reducing the required bias and readout lines to a single microwave feed line.
