The Design and Implementation of Multiple Services Tracking and Parallelly Testing in CMMB System
Lei Guo, Xian Yi Yineng · Applied Mechanics and Materials · 2013
We need to track and detect all kinds of business when we prepare to have a test on the network in the Mobile Digital Multimedia Broadcasting System. This paper raise a way can parallelly test all the physical parameters such as RSSI, multipath, constellation diagram, BER and SNR of the service time slot of every frame in CMMB system by making a research on the traditional way of multiple services tracking and parallelly testing in CMMB system.On the basis of traditional way, we increase parity service discriminant moduleodd service parameters test module and even service parameters test module and make reasonable control scheme that odd service parameters test module and even service parameters test module test and receive the input data alternately in time ,that is to say, they independently make internal data processing, which making a good solution to the problems that the occupation of the system resource and insufficient data processing time.
