Outage Probability Analysis for OTFS with Finite Blocklength
Xin Zhang, Wensheng Lin, Lixin Li +2
Orthogonal time frequency space (OTFS) modulation is widely acknowledged as a prospective waveform for future wireless communication networks.To provide insights for the practical…
Emergency Communication: OTFS-Based Semantic Transmission with Diffusion Noise Suppression
Kexin Zhang, Xin Zhang, Lixin Li +3
Due to their flexibility and dynamic coverage capabilities, Unmanned Aerial Vehicles (UAVs) have emerged as vital platforms for emergency communication in disaster-stricken areas.…
SAFE: Semantic Adaptive Feature Extraction with Rate Control for 6G Wireless Communications
Yuna Yan, Lixin Li, Xin Zhang +3
Most current Deep Learning-based Semantic Communication (DeepSC) systems are designed and trained exclusively for particular single-channel conditions, which restricts their adapta…
Outage Probability Analysis for OTFS in Lossy Communications
Xin Zhang, Wensheng Lin, Lixin Li +3
This paper analyzes the outage probability of orthogonal time frequency space (OTFS) modulation under a lossy communication scenario. First of all, we introduce the channel model a…
FSSC: Federated Learning of Transformer Neural Networks for Semantic Image Communication
Yuna Yan, Xin Zhang, Lixin Li +4
In this paper, we address the problem of image semantic communication in a multi-user deployment scenario and propose a federated learning (FL) strategy for a Swin Transformer-base…
