Research And Implementation Of Partial RF Measurements Based On Wcdma Terminal RF Test Instruments

As one of the most important3rd generation communication technical standards, WCDMA still takes the major share of the telecommunications market around the world. Thus WCDMA terminal plays a role in the mobile communition system. Before putting into maket, WCDMA terminal needs to go through a series of test cases, including RF perfomances testing. Emerging with tide, WCDMA terminal RF test instruments can help in design, research and production of terminals. As the testing efficiency enhanced dramatically, this specialized tester is wide populared by terminal producers.This research topic is an important part of WCDMA terminal Tester, covering the work of the design and implementation of inner loop power contrlol test and promotion of paralleling measurement. With substantial work of product research, protocol study, simulation, implementation and testing, this paper has achieved the expected project objectives.The contents of the thesis are presented as follows:The thesis firstly stated the background of the research and summarized the the main work based on the WCDMA industrial development. Secondly, it illustrated the measurement items of WCDMA RF test, described the framework of platform and briefly analyzed the measurements to be implemented. Then, it focused on the research and implementation of inner loop power control test and algorithms to promote paralleling measurement. It presented the contents to study, analyzed the key processing algorithms, designed the test procedures for inner loop power control test and modified the test scheme for paralleling measurement. Also validations of algorithms and test procedures are achieved. Finally, it came to a conclusion and prospected the terminal RF test instuments.All the achievements in this thesis have been successfully applied to the WCDMA terminal RF tester and achieved sound results. The marketing of this product fills the gap in the domain of WCDMA terminal tester in our country and thus leads to positive competetion with international manufacturers.
