摘要:

近年来,基于深度学习(DL)的语义通信方法已经被探索用于图像、文本和语音的高效传输。与传统的无线通信侧重于传输抽象符号的方法相比,语义通信方法试图通过仅发送源数据的语义相关信息来实现更好的传输效率。在本文中,我们考虑面向语义的语音文本传输。我们提出了一种新的端到端的DL为基础的收发器,其中包括一个基于注意力的软对齐模块和冗余删除模块来压缩传输的数据。特别是,前者只提取与文本相关的语义特征,后者进一步丢弃语义冗余内容,与现有方法相比,大大减少了语义冗余量。我们还提出了一个两阶段的训练计划,这加快了建议的DL模型的训练。仿真结果表明,我们提出的方法优于现有的方法在接收文本的准确性和传输效率。此外,该方法还具有较小的模型大小和较短的端到端的运行时间。

英文摘要:

Deep learning (DL) based semantic communication methods have been explored for the efficient transmission of images, text, and speech in recent years. In contrast to traditional wireless communication methods that focus on the transmission of abstract symbols, semantic communication approaches attempt to achieve better transmission efficiency by only sending the semantic-related information of the source data. In this paper, we consider semantic-oriented speech to text transmission. We propose a novel end-to-end DL-based transceiver, which includes an attention-based soft alignment module and a redundancy removal module to compress the transmitted data. In particular, the former extracts only the text-related semantic features, and the latter further drops the semantically redundant content, greatly reducing the amount of semantic redundancy compared to existing methods. We also propose a two-stage training scheme, which speeds up the training of the proposed DL model. The simulation results indicate that our proposed method outperforms current methods in terms of the accuracy of the received text and transmission efficiency. Moreover, the proposed method also has a smaller model size and shorter end-to-end runtime.
