Abstract

The invention discloses a mobile communication terminal based on a ''Big Dipper'' satellite, which comprises an FPGA (field programmable gate array) chip XC5VLX50T, a voice coding and decoding chip AMBE2000 and a front-end element PCM3500, wherein the XC5VLX50T is respectively connected with the AMBE2000 and the PCM3500 through programmable interfaces, and controls the AMBE2000 through reset control signals, so that the XC5VLX50T starts first in the normal operation, then the XC5VLX50T controls the AMBE2000 to start in an appointed manner, and finally, the XC5VLX50T sends information contents to the AMBE2000 through the programmable interfaces, and controls the information contents of the PCM3500. In addition, the invention also provides an XC5VLX50T-AMBE2000 information interaction method in the satellite mobile communication terminal, so that the Big Dipper mobile communication terminal has the advantages of high voice quality and high real-time property.

Description

technical field [0001] The invention relates to the field of satellite mobile communication, in particular to a "Beidou"-based satellite mobile communication terminal and a method for information interaction between XC5VLX50T and AMBE2000 in the terminal. 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, compu...
