The Study Of Optimization System For TD-LTE Terminal Chip

As TD-LTE (Global 4G standard), which is proposed by China, becomes the only standard of TDD broadband mobile communication system for 3GPP organization, many communication enterprises begin to set up TD-LTE R&D labs, which include a series of intustry chains, such as system equipments, instruments, chips, terminals, RF equipments and so on. However, the R&D of chips and terminals falls behind that of other industrial chanis. The bottleneck of TD-LTE is to improve the R&D of chips and terminals, in order to ensure the industrial process of TD-LTE.Focusing on the terminal chip of TD-LTE from Innofidei, this thesis establishes two kinds of communication network. One is by the combination of Agilent spectrum device and signal source, and the other is to utilize communication test-network by ZTE’s TD-LTE base stations. A suit of software system is realized finally to study the optimization system of TD-LTE terminal chip by combining test of two communication networks. The architecture of software is MFC, with the integration of Winpcap and VISA interface language to control hardware environment. The optimized software system integrates API developing package of Agilent, has much functions to adjust communication indexes, such as OFDM constellation, signal power, center frequency offset, side band interference, and can be cooperative with hardware environment to optimize TD-LTE terminal chip.
