Channel-Aware Deep Joint Source-Channel Coding for Multi-Task Oriented Semantic Communication

Existing deep learning (DL)-based semantic communication generally employs deep neural networks (DNNs) for semantic extraction at a fixed dimension and incorporates channel state information (CSI) to facilitate semantic transmission. However, the optimal dimension of the semantic information to tran...
