基于自适应通用Transformer的语义通信

Semantic Communication with Adaptive Universal Transformer

Qingyang Zhou, Rongpeng Li, Zhifeng Zhao, Chenghui Peng, Honggang Zhang

摘要:

随着深度学习(DL)的发展,自然语言处理(NLP)使我们能够分析和理解大量的语言文本。因此,我们可以实现语义通信的联合语义源和信道编码在噪声信道的帮助下。然而,现有的实现这一目标的方法是使用NLP的固定Transformer,而忽略了每个句子所包含的语义信息的差异。针对这一问题,提出了一种基于通用Transformer的语义通信系统。与传统的Transformer相比,通用Transformer引入了自适应循环机制。通过引入循环机制,新的语义通信系统可以更灵活地传输不同语义信息的句子,在各种信道条件下实现更好的端到端性能。

英文摘要:

With the development of deep learning (DL), natural language processing (NLP) makes it possible for us to analyze and understand a large amount of language texts. Accordingly, we can achieve a semantic communication in terms of joint semantic source and channel coding over a noisy channel with the help of NLP. However, the existing method to realize this goal is to use a fixed transformer of NLP while ignoring the difference of semantic information contained in each sentence. To solve this problem, we propose a new semantic communication system based on Universal Transformer. Compared with the traditional transformer, an adaptive circulation mechanism is introduced in the Universal Transformer. Through the introduction of the circulation mechanism, the new semantic communication system can be more flexible to transmit sentences with different semantic information, and achieve better end-to-end performance under various channel conditions.
