Research on performance testing of telecommunication terminals and chips

LI Lei;ZHENG Yang;  
With a deep and rapid development of telecommunication industries, it nowadays poses a much higher requirement on the design of terminals and chips, not only focus on throughput or delay, but also a better comprehensive users' experience.It is always one of key issues to telecommunication manufacturers on how to improve the quality of productions through performance testing. In this paper, several commonly used testing technologies are first briefly introduced. Then a novel concept of virtual drive test(VDT) is presented, which is aimed to rebuild the outdoor wireless environment, such as high-speed railway or bad coverage scenarios, in lab based on channel modeling theory. Using VDT system, devices can be tested under different virtual scenarios to simulate what a user experiences in the real world. VDT technology has a bright future but it still faces severe challenges under the forthcoming the fifth generation.
