SNR-EQ-JSCC: Joint Source-Channel Coding With SNR-Based Embedding and Query [PDF]

open access: yesIEEE Wireless Communications Letters
Coping with the impact of dynamic channels is a critical issue in joint source-channel coding (JSCC)-based semantic communication systems. In this paper, we propose a lightweight channel-adaptive semantic coding architecture called SNR-EQ-JSCC. It is built upon the generic Transformer model and achieves channel adaptation (CA) by Embedding the signal ...
