This paper comprehensively and deeply studies the application of asymmetric physical layer network coding in the field of UAV communication, analyzes its technical principle, advantages and challenges in actual deployment, and puts forward the optimization strategy. With the rapid development of UAV technology, its application scenarios are constantly expanded, which puts forward higher requirements for the performance, safety, reliability and efficiency of communication system. Asymmetric physical layer network coding as an innovative communication technology, through the introduction of asymmetric coding mechanism in the network physical layer, not only can effectively improve the throughput of UAS communication system, reduce transmission delay, but also enhance its ability to resist interference and environmental changes. In this paper, the basic concept of network coding is described in detail, and the embodiment of asymmetry in network coding and its theoretical advantages and potential applications are introduced. Then, this paper deeply analyzes the specific application effects of asymmetric coding in UAV communication, including improving communication system performance, enhancing anti-interference ability, optimizing bandwidth utilization and reducing transmission delay. However, the application of asymmetric coding in UAV communication also faces many challenges, such as high complexity of key management and distribution, limited computing resources, prominent security and reliability issues, and insufficient standardization and interoperability. To solve the above problems, this paper puts forward a series of optimization suggestions, including strengthening key management and distribution mechanism, improving computing efficiency and optimizing resource allocation, enhancing security and reliability, and promoting standardization and interoperability.
