| 摘 要： | 在软件接收机的研究中,为了实现在GPS或者北斗模式下基带对射频前端数据的采集,在Altera公司的Cy-cloneⅢ系列FPGA器件上采用VERILOG语言编写了SPI总线协议,完成了对射频前端芯片GPS/北斗两种工作模式的切换,使基带可以随时获得两种模式下的数据。通过验证,采集来的数据与期望的结果一致。同时为工程设计提供了一种原型,也为进一步的工程开发奠定了基础。

| Abstract: | In the study of software receiver,for receiving data from RF front-end in the model of GPS or CNSS,SPI bus protocol is implemented by using Verilog HDL on ALTERA′s Cyclone III FPGA platform,and the switch between GPS and CNSS is completed so that the baseband can obtain data from GPS/Compass at any time.The collected data are consistent with expectations through a verification.At the same time,it can be taken as a prototype,which can be used in a further profound exploitation in EDA project. |
