摘要：為了从基础理论层面诠释通信导航融合的原理，为通信导航融合研究提供引导和理论支撑，从无线电传播的理论基础和代表性公式入手，综合考虑传输和测量2个核心要素，推导出通信导航一体化联合似然概率、信道容量、网络容量3个统一表征公式;以此为基础，选择了通信导航一体化波形并针对性设计了一体化接收机架构;提供了一体化系统架构和资源管理方案2个角度的一体化系统实现思路，最终构建了由一体化表征公式、一体化链路设计、一体化系统构成的通信导航融合体系。结果表明，所建构体系实现了数学机理、物理承载、应用实现3个层面的通导融合，描绘了通信导航融合的整体框架，涵盖了通信导航融合研究的主要领域，可为通信导航融合发展涉及的信号体制、交互协议、硬件设计等方面的研究提供参考和支撑。

Abstract：In order to interpret the principles of communication and navigation fusion from the basic theoretical level and provide guidance and theoretical support for the research of communication and navigation fusion，starting from the theoretical basis and representative formulas of radio propagation，and comprehensively considering the two core elements of transmission and measurement，three unified presentation formulas of communication and navigation integration combining likelihood probability，channel capacity，and network capacity were derived.Based on this，the integrated waveform of communication and navigation was selected，and the integrated receiver architecture was designed specifically.Then，an integrated system implementation idea from two perspectives of integrated system architecture and resource management scheme was provided.Finally，a communication and navigation fusion system consisting of integrated representation formula，integrated link design，and integrated system was constructed.The results show that the system realizes the integration of communication and navigation at three levels：mathematical mechanism，physical bearing and application realization，the overall framework of communication and navigation fusion is depicted，and the main fields of communication and navigation fusion research are covered.It can provide reference and support for the research of signal system，interactive protocol，hardware design and other aspects involved in the development of communication and navigation integration.

中国将在2035年前后建设更为泛在、更加融合、更加智能的国家综合PNT（pointing，navigation，timing）体系，而通信与导航的融合将是其重要发展方向和建设内容之一[1-3]。5G移动通信系统也明确了需要实现一定精度的定位能力[4]。此外，在未来天地一体化信息网络的建设中，通信导航一体化融合是必要途径之一[5-7]。

目前已建设了一系列的具有通信导航一体化特点的系统，以A-GPS、星基导航增强系统（SBAS）、地基增强系统（GBAS）等为代表的增强系统，这类系统的基本思想是利用通信链路播发导航辅助增强信息，仅在应用层实现了通信与导航的初步融合[8]。……
