Abstract

The invention discloses an information interactive test method for a satellite mobile communication terminal based on a Beidou. The method is used for testing an analog interface of an FPGA of the satellite mobile communication terminal based on the Beidou. The method is that: in a work state, the FPGA sets a memory number value of a position 0 of an RAM corresponding to an HPI in a DSP through an analog HPI interface and when a set time reaches, the DSP checks whether a memory number value of the position 0 of the RAM corresponding to the HPI in the DSP is the number value, if yes, the analog interface is correct. The information interactive test method for the satellite mobile communication terminal based on the Beidou enables performance of the analog HPI interface and performance of information interaction of an analog resetting control interface of the FPGA of the satellite mobile communication terminal based on the Beidou to be well tested so that information interaction performance of the satellite mobile communication terminal based on the Beidou is ensured.

Description

technical field [0001] The invention relates to the field of satellite mobile communication, in particular to a "Beidou"-based satellite mobile communication terminal information interaction testing method. Background technique [0002] The low-frequency part of the digital radio system uses digital circuits. Compared with the traditional radio system, the A / D and D / A conversions of the software radio system are moved to the intermediate frequency and as close as possible to the radio frequency end. The software defined radio replaces the dedicated digital circuit with powerful programmable FPGA and DSP devices, making the system hardware structure and function relatively independent. The advanced field programmable array FPGA technology lies in the compact footprint capable of high-speed processing, while maintaining the flexibility and programmability of software radio technology. FPGAs are advantageous in high-speed, compute-intensive, reconfigurable applications (FFT, F...
