Vector Quantized Semantic Communication System

2023 · IEEE Wireless Communications Letters

Although analog semantic communication systems have received considerable attention in the literature, there is less work on digital semantic communication systems. In this letter, we develop a deep learning (DL)-enabled vector quantized (VQ) semantic communication …

Federated Generative-Adversarial-Network-Enabled Channel Estimation

2023 · Intelligent Computing

Accurately estimating channel state information is essential for meeting the quality-of-service requirements of modern applications and scenarios. Deep learning techniques have proven effective in acquiring channel conditions with low pilot overhead in massive connectivity scenarios. …
