Rethinking Modern Communication from Semantic Coding to Semantic Communication
Kun Lu, Qingyang Zhou, Rongpeng Li +4
Modern communications are usually designed to pursue a higher bit-level precision and fewer bits while transmitting a message. This article rethinks these two major features and in…
1.71 Tb/s Single-Channel and 56.51 Tb/s DWDM Transmission over 96.5 km Field-Deployed SSMF
Fabio Pittala, Ralf-Peter Braun, Georg Boecherer +11
We report an industry leading optical dense wavelength division multiplexing (DWDM) field trial with line rates per channel exceeding 1.66 Tb/s using 130 GBaud dual-polarization pr…
ICINet: ICI-Aware Neural Network Based Channel Estimation for Rapidly Time-Varying OFDM Systems
Yi Sun, Hong Shen, Zhenguo Du +2
A novel intercarrier interference (ICI)-aware orthogonal frequency division multiplexing (OFDM) channel estimation network ICINet is presented for rapidly time-varying channels. IC…
Passive Beamforming Design for Intelligent Reflecting Surface Assisted MIMO Systems
Chenghao Feng, Wenqian Shen, Xinyu Gao +1
Intelligent reflecting surfaces (IRSs) constitute passive devices, which are capable of adjusting the phase shifts of their reflected signals, and hence they are suitable for passi…
Real-time Streaming Wave-U-Net with Temporal Convolutions for Multichannel Speech Enhancement
Vasiliy Kuzmin, Fyodor Kravchenko, Artem Sokolov +1
In this paper, we describe the work that we have done to participate in Task1 of the ConferencingSpeech2021 challenge. This task set a goal to develop the solution for multi-channe…
SNR-adaptive deep joint source-channel coding for wireless image transmission
Mingze Ding, Jiahui Li, Mengyao Ma +1
Considering the problem of joint source-channel coding (JSCC) for multi-user transmission of images over noisy channels, an autoencoder-based novel deep joint source-channel coding…
