Fusion-Based Multi-User Semantic Communications for Wireless Image Transmission over Degraded Broadcast Channels

Understand

Degraded broadcast channels (DBC) are a typical multi-user communications scenario.

• There exist classic transmission methods, such as superposition coding with successive interference cancellation, to achieve the DBC capacity region.
• However, semantic communications method over DBC remains lack of in-depth research.
• To address this, we design a fusion-based multi-user semantic communications system for wireless image transmission over DBC in this paper.
