Analog Microwave Transmission Network Digital Transformation And Realization

Along with the development and progress of science and technology, production of radio and television programs are gradually moving toward digital, Digital Video Broadcasting DVB. Digital Audio Broadcasting DAB, high-definition television HDTV and other digital radio and television programs are operational. Digital programs need digital transmission means. SDH microwave transmission to large capacity, long-distance, wide range of digital radio and television signals transmitted to the entire province. SDH microwave digital radio and television signal transmission solutions province-wide coverage of the major options.In recent years, hostile forces attacking satellites, blocking optical cables,which has seriously effect on the safety of broadcast radio and television work. With an increasingly grim security situation in the broadcast, microwave transmission increasingly becoming an important guarantee for security possible. Microwave transmission network of radio and television undertake major political responsibility is the safety and security of the state and local early warning system, is the lifeblood of political tasks and the completion of one of the channels, and radio and television business is to provide a platform for high reliability transmission security, resist natural disasters and man-made destruction is important to resist the means of transmission.In this paper, in accordance with the Digital Microwave engineering process of Radio and Television Bureau of Shandong Province, from the program to determine routing design lines, the fsding analysis, counter-measures, routes expand, business expand their in areas such as analysis. This paper from the first chapter of microwave digital simulation reviewed the overall situation of reform, and a major research content. In the II chaapterof this paper, the Radio and Television Bureau of Shandong Province simulation program proposed microwave digital transformation and rehabilitation programs for identified analyzed.The combined use of SDH and PDH microwave rehabilitation programs. Chapter III of the province routing microwave circuit design and calculation of the transmission lines. Chapter IV of the station from the long decline in problem solving and analysis. Chapter V of the expansion and functional lines to expand.
