The content of this paper is based on the project of digital microwave communication system in Yibin, Sichuan Province. The author of the paper is the director of the project. First of all, a brief introduction of techniques and applications of digital microwave communication system is presented in the paper. There is also a synopsis of the composition and key parameters of the system. According to the experiences of construction, the notes and methods are proposed during the construction of the digital microwave communication system. Based on the requirement analysis of the project, the paper calculates related parameters in detail. The design and implementation of the construction project of digital microwave communication system in Yibin, Sichuan Province is discussed at large, which exploits the parameters above and is compatible to the national standards of microwave communication system. The paper presents the debug method, test project and test result of the system. It also sums up some measures to resolve the failures of the system when it is running.
