Implementation Of Terminal Signal Quality Measurement In CDMA2000-1X Reverse Channel

CDMA2000-1X is an important part of the wireless communication system and has always occupied a solid market share. As an indispensable part of the CDMA2000 industrial chain, the CDMA2000-1X terminal signal quality measurement provides an effective verification and measurement scheme for the design and production environment of the CDMA2000-1X terminal, and promotes the development of the terminal measurement industry. Therefore, it is very necessary to design and implement the CDMA2000-1X terminal transmitting signal quality measurement algorithm.Based on the research of CDMA2000 physical layer protocol and measurement protocol, this paper implements signal quality measurement algorithm in CDMA2000-1X reverse channel, calculates the time consuming of the measurement process and optimizes the computing time on the basis of the result.The main content of the article are as follows:First of all, it introduce the background and significance of the thesis, the hardware and software architecture of the terminal communication and the way of generating signal in CDMA2000-1X reverse channel which will be used in the following chapters.Secondly, it implements the measurement algorithm in CDMA2000-1X reverse channel and calculates the operation time in the calculation process.Compare the contents of the paper with another company's test set for comparative analysis and validation.Finally, it summarizes the contents of the paper and describes the prospect and the direction of the terminal testing instruments on the basis of the results of the research.The achievements of the paper have been used in commercial terminal communication test set which has passed a variety of test cases and has been widely recognized by terminal authentication.
