Embodiment Construction

[0027] The present invention will be described in detail below by taking TD-SCDMA as an example.

[0028] Such as Figure 4 Shown, the testing device of the present invention comprises TR-LINK SERDES (Serializer / Deserializer, serial / deserializer) interface, FPGA chip, receive digital signal processor (DSP), send digital signal processor (DSP), PCI interface, Storage modules and power supplies. TR-LINKSERDES interface is a link interface that converts 16bits parallel data with TR-LINK protocol and LVDS serial high-speed signal to each other. It is used to transfer parallel data to standard LVDS serial data when sending and standard LVDS serial data to parallel when receiving. Data conversion. There are three pieces of SERDES in the present invention. The LVDS of the present invention can also be other serial high-speed transmission interfaces, and any communication interface with a data conversion function can be used in the present invention, such as a photoelectric convers...

Abstract

The apparatus comprises: a data exchanging interface used for intercommunication with external data; a FPGA module used for analyzing and giving out the received data, for packaging and giving out the transmitted data and for control the clock signal of the apparatus; a memory module used for buffering the data after the analyzing and before the packaging and relevant instruction data; a DSP used for reading out the data in the memory module and making relevant process, and for processing the transmitted data and transmitting it to the FPGA. The system completes the relevant testing based on the apparatus above. The invention can be used in TD=SCDMA, CDMA2000 and WCDMA system.

Description

technical field [0001] The invention relates to a baseband protocol data testing device and a corresponding system in a third generation mobile communication system (3G). Background technique [0002] In recent years, the third-generation mobile communication has always been the focus of people's attention, and the third-generation mobile communication standards have gradually formed three mainstream standards after continuous integration, namely WCDMA (Wideband Code Division Multiple Access) proposed by Europe, and WCDMA (Wideband Code Division Multiple Access) proposed by the United States. CDMA2000 and TD-SCDMA proposed by China. Products complying with the corresponding standard protocols have emerged one after another, and the commercialization process of base station products based on TD-SCDMA, which is dominated by Datang Mobile Communications, has entered the final stage. Such as figure 1 As shown, the structure of the TD-SCDMA system mainly includes three parts: c...
