This paper reviews the application and development of AI technology in the physical layer of wireless communication in recent years. With the rapid development of information technology, wireless communication is facing new requirements such as multi-scenarios, high reliability and low latency, which constantly challenges the traditional algorithms and system architecture of the wireless physical layer. On the other hand, the breakthrough of deep learning in computer vision, natural language processing and other fields, leads to the research of applying artificial intelligence technologies to the physical layer of wireless communication. By virtue of the characteristics of data-driven modeling, deep learning based models are promising to assist conventional physical layer algorithms and solve the difficulty of channel modeling. This paper extensively and thoroughly investigates the latest academic research achievements of applying deep learning to wireless physical layer at home and abroad, and summarizes the common schemes and performance advantages of deep learning for modulation recognition, channel decoding, signal detection and so no. The details of a new end-to-end wireless communication framework are also presented. This paper reveals the feasibility and great potential of applying learning for wireless communication, and also points out current problems and challenges, such as lack of reliable theoretical analysis, specialized architectures for wireless communications, and specific implementation schemes, and thus indicates the future research and development direction in this field.
