Variational Source-Channel Coding for Semantic Communication
Yulong Feng, Jing Xu, Liujun Hu +2
Semantic communication technology emerges as a pivotal bridge connecting AI with classical communication. The current semantic communication systems are generally modeled as an Aut…
OTFDM: A Novel 2D Modulation Waveform Modeling Dot-product Doubly-selective Channel
Yihua Ma, Zhifeng Yuan, Yu Xin +4
Recently, a two-dimension (2D) modulation waveform of orthogonal time-frequency-space (OTFS) has been a popular 6G candidate to replace existing orthogonal frequency division multi…
Highly Efficient Waveform Design and Hybrid Duplex for Joint Communication and Sensing
Yihua Ma, Zhifeng Yuan, Shuqiang Xia +2
Joint communication and sensing (JCAS) is a very promising 6G technology, which attracts more and more research attention. Compared with communication, radar has many unique featur…
Dual connectivity and standalone modes for LTE-U
Yajun Zhao, Yu-Ngok Ruyue Li, Liujun Hu +1
Long-Term Evolution in unlicensed bands (LTE-U) has been considered as an effective way of offloading traffic from licensed bands. This paper discusses the scenarios, requirements…
