摘　　要：针对一般调制平台互联性差、灵活性差、复用性差等问题,采用软硬件协同设计和部分动态可重配置等技术,设计了一种基于Zynq-7000和AD9361的通用调制平台。采用16APSK和QPSK的调制方式对通用调制平台的设计进行验证,其中平方根升余弦成形滤波器采用查找表形式的多相滤波器结构实现,该实现方法只用到加法运算。测试结果表明,在不同Zynq-7000开发板和不同调制方式下,替换部分硬件功能模块和修改软件配置,平台均能正常工作。与传统调制平台相比,本平台的设计以及功能实现具有灵活性强、复用性高等特点,具有广阔应用前景。For the problems of poor connectivity,flexibility,and reusability of general modulation platforms,a general modulation platform based on Zynq-7000 and AD9361 is designed by the technologies of hardware-software co-design and partial dynamic reconfiguration.The modulation methods of 16 APSK and QPSK are used to verify the design of the universal modulation platform.The square root raised cosine shaping filter is implemented by the multi-phase filtering structure in the form of look-up table,which only uses the addition operation.The test results show that the platform can work normally with the replacement of some hardware function modules and the modification of software configuration under different modulation modes and different Zynq-7000 development boards.Compared with traditional modulation platform about design and function realization,the designed platform has the characteristics of high flexibility,strong reusability and it has wide application prospect.
