Abstract


Commercialization of TD-SCDMA is being carried out domestic fire, such as tea . TD-SCDMA industry chain as an integral part , TD-SCDMA terminals tester applications throughout the TD-SCDMA terminal design , production, and links of network authentication , and with the TD-SCDMA industry continues to evolve , the demand is growing. Through theoretical research, algorithm design, coding and debugging integration processes, this paper completed the \The main contents are as follows : First, the analysis of the terminal RF conformance test for the significance of the development of communication industry , and TD-SCDMA terminal RF conformance test system test functions possess a brief introduction. Two , the focus of EDGE terminal transmitter modulation quality test items is achieved. First proposed the modulation quality measurement algorithm flow test items as well as various test index calculation method, and then through simulation and theoretical analysis of the demodulation algorithm and EVM algorithm is improved , according to the terminal RF conformance test characteristics to achieve the most efficient modulation quality testing algorithm, both to ensure the minimum amount of computation algorithms , while achieving a resistance offset , low SNR loss , low test uncertainty and other targets. Finally, the function for automatic frequency calibration of the algorithm for further improvement. Third, in the analysis and summary of TD-HSUPA terminal RF conformance test specification , based on the HSUPA terminal RF conformance test function design and implementation. Four , and finally a brief summary on the whole were reviewed and discussed. The research results have been applied to the commercial terminal tester design and implementation of them . So far, the instrument has passed various tests , stable operation . Have been a number of chip and handset manufacturers are used , a good response .
