摘　　要：为了解决传统无线电平台分立器件繁多、功能单一、开发周期长的问题,提出了一种搭载现场可编程门阵列(field programmable gate arrays,FPGA)和AD9361的软件无线电平台的实现方法。以FPGA(KINTEX-7)为主控芯片,表述了MicroBlaze嵌入式软核与相应串行外设接口(serial peripheral interface,SPI)、通用输入输出(general purpose input\output,GPIO)接口以及数据接口的设计思路,并对AD9361进行了芯片配置,实现了FPGA基带模块与AD9361之间的数据交互。功能测试结果表明,此平台能够根据需求更改数据调制方式与收发通道参数配置,且具有良好的收发性能。与传统无线电平台相比,此平台具有灵活性高、通用性强等特点,能够适用于多种应用场景。In order to solve the problems of many discrete devices,single function and long development cycle in traditional radio platforms,we propose an implementation method of software defined radio platform equipped with field programmable gate arrays(FPGA)and AD9361.The platform uses FPGA(KINTEX-7)as the main control chip.This paper describes the design idea of MicroBlaze embedded soft core and corresponding serial peripheral interface(SPI),general purpose input\output(GPIO)interface and data interface,and configures the chip of AD9361 to realize the data interaction between FPGA baseband module and AD9361 chip.The function test results show that this platform can change the data modulation mode and the parameter configuration of the transceiver channel according to the requirements,and has good transceiver performance.Compared with the traditional radio platform,this platform has the characteristics of high flexibility,strong versatility,and can be applied to various application scenarios.
