… in realizing digital modulation in semantic communications. To tackle the above challenges
in NN-based digital semantic communications, we propose a joint coding-modulation (JCM) …

… Then, based on the proposed algorithm, we develop an adaptive modulation scheme in
semantic communication systems. However, when the channel condition becomes too bad, …
