Multiband Real-Time Coherent Optical OFDM Reception up to 110 Gb/s with 600-km Transmission

open access: yesIEEE Photonics Journal, 2010
We demonstrate field-programmable gate array (FPGA)-based multiband orthogonal frequency-division multiplexing (OFDM) signal reception after 600-km standard single-mode fiber (SSMF) transmission and 400-ps differential-group delay (DGD) at 110-Gb/s.

Flexible organic crystals: From rational design to applications

open access: yesFlexMat, EarlyView.
Abstract Flexible organic crystals (FOCs) represent an innovative category of organic crystalline materials distinguished by their remarkable ability to undergo elastic deformation or bending when subjected to external forces, all while maintaining the integrity of their crystalline order.

Non-Orthogonal Multicarrier Waveform for Radar With Communications Systems: 24 GHz GFDM RadCom

open access: yesIEEE Access, 2019
In this paper, we propose the usage of Generalized Frequency Division Multiplexing (GFDM), a non-orthogonal multicarrier waveform for radar. We presented a novel method that cancels the effect of interference caused by the non-orthogonality of GFDM ...

Plasma proteomic profiling and molecular clustering reveal immune‐defined prognostic subtypes in lung adenocarcinoma

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Lung adenocarcinoma shows considerable heterogeneity in disease progression and therapeutic response. Here, the authors analyzed tumor samples through proteomic profiling and applied network‐based clustering. They identified two distinct patient groups with different demographic, clinical, and molecular characteristics.

The synchronization of the orthogonal frequency division multiplexing system

open access: yesDoklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2019
The results presented research OFDM system synchronization by using one of the basic properties of the continuous Fourier transform, characterized by the duality between a convolution in the time domain, and multiplying the frequency domain, which is not

Identity‐Enabled CDMA LiDAR for Massively Parallel Ranging with a Single‐Element Receiver

open access: yesLaser &Photonics Reviews, EarlyView.
A novel LiDAR system integrates CDMA modulation with a single‐element detector to achieve massive channel parallel 3D imaging. By using a user identification code and a correlation‐based feedback loop, it overcomes signal collisions and the near‐far problem.
