基于AD9364的通用软件无线电平台的FPGA设计与实现

FPGA design and implementation of universal software defined radio system based on AD9364

本论文基于搭建一种具有优秀可移植性的高性能通用软件无线电平台的目的。以亚诺德半导体有限公司的射频捷变收发器AD9364为核心器件代替由分立器件搭建射频收发端,并采用了在Vivado环境用HDL语言对FPGA进行开发的方法,完成了对AD9364的控制和数据收发操作。FPGA与AD9364间的控制通路分别采用了利用UART接口,以及利用ROM IP核的进行AD9364寄存器配置的两种方法,数据接口采用了LVDS兼容模式。利用此平台实现了16APSK调制。平台通过资源占用分析和系统收发试验。得出了通用软件无线电平台的能完成数据收发且具有优秀可移植性的结论。

The purpose of this paper is to build a high-performance and universal software radio platform with excellent portability. The system adopts the Analog Devices,Inc.'s highly integrated radio frequency(RF) Agile Transceiver AD9364 as a core device instead of the separate device. It is implemented on FPGA by HDL in Vivado,and could control AD9364 and transfer the data. UART interface,as well as the ROM IP core are used to design and implement the AD9364 register configuration. The data interface operates in low-voltage differential signal(LVDS)compatible mode.This platform could achieve 16 APSK modulation. Through the resource utilization analysis and data transmission test,it is concluded that this universal software radio platform could complete the data transceiver and has excellent portability.
