Design And Implementation Of Coverage Quality Measurement System For Wireless Radio And Television Signals

Frequency modulation broadcast, medium wave broadcast ,analog television ,China Terrestrial Television Broadcasting(CTTB) and China Mobile Multimedia Broadcasting(CMMB) are the main ways of wireless radio and TV broadcasting and people can listen to the radio and watch TV in outdoor or in vehicles unlike wired TVs.The Evaluation of Coverage Quality for Wireless radio and television signals is the primary concern of experts who work in radio and TV broadcasting field. Under normal circumstances coverage quality is measured manually. However with the increase number of the radio and television programs and the increase of measurement workload, manual measurement method has been unable to meet the needs of coverage quality measurement.This paper proposed a design and implementation of an automatic coverage quality measurement system. It can measure the quality of signals and evaluate the coverage quality without supervision, which can save a lot of time and greatly increase the efficiency. With the integration of GIS systems, the system provides a more user friendly interface to display the result of signal coverage measurement.According to the process of software development, the design and implementation of the system can be divided into three main steps: Requirement and Need Analysis, Global Design and Module Design which includes the data acquirement and storage strategy, GIS module implementation and radio programs recording strategy.
