基于FPGA的SOPC系统DAB发射端硬件实现

摘要

本文设计基于FPGA芯片EP3C16Q240C8N的片上可编程系统,该系统可用于实现IFFT运算和接口模块,利用可嵌入到此FPGA芯片的NiosII软核处理器来实现数据传输和控制。功能电路中的ADI的数字上变频芯片AD9957和可控增益芯片AD8369用于实现DAB基带信号的上变频和信号放大。这套DAB发射机电路板尺寸为100cm*160cm,经过测试,能很好的完成发射,具有较高的可靠性。%In this paper,the design based FPGA chip EP3C16Q240C8N of system on a programmble chip for IFFT and interface modules,and use NiosII soft-core processors to achieve data transmission and control.AD9957 and AD8369 were used to implement digital up-converter of DAB baseband signal and signal amplification in functional circuit.The DAB transmitter circuit board size is only 100cm * 160cm,tests show that this circuit transmit DAB signal with high reliability.
