ReLViC: Loss-Resilient Learned Video Coding with Dispersed Packetization and Controllable Packet Dependencies
Xuyang Chen, Daquan Feng, Xianfu Chen +1
Packet loss can severely impair learned video coding because missing latent tokens compromise both spatial reconstruction and temporal prediction. We present ReLViC, a loss-resilie…
Recall Gabor Communication Theory and Joint Time-Frequency Analysis
Xiang-Gen Xia
In this article, we first briefly recall Gabor's communication theory and then Gabor transform and expansion, and also its connection with joint time frequency analysis.
QoE Optimization for Semantic Self-Correcting Video Transmission in Multi-UAV Networks
Xuyang Chen, Chong Huang, Daquan Feng +3
Real-time unmanned aerial vehicle (UAV) video streaming is essential for time-sensitive applications, including remote surveillance, emergency response, and environmental monitorin…
Rethink Delay Doppler Channels and Time-Frequency Coding
Xiang-Gen Xia
In this paper, we rethink delay Doppler channels (also called doubly selective channels). We prove that no modulation schemes (including the current active VOFDM/OTFS) can compensa…
A Note On the Clark Conjecture On Time-Warped Bandlimited Signals
Xiang-Gen Xia
In this note, a result of a previous paper on the Clark conjecture on time-warped bandlimited signals is extended to a more general class of the time warping functions, which inclu…
