摘　　要：为了提高DSP系统的开发效率,引入了现代DSP技术,并由此设计了QPSK调制器。依据QPSK调制的基本原理,利用MATLAB/Simulink DSP Builder和QuartusII搭建模型,在模块的形成方式上,采用DSP Builder中的模块代替VHDL编程,在同一平台上实现了系统建模和硬件实现的有机结合,然后利用ALTERA公司提供的Signal Compile进行编译,产生VHDL源程序,同时,采用ALTERA公司的Cyclone系列芯片EP2C35F672C6N实现QPSK调制。结果表明,该方法提高了设计的灵活性,通过软件仿真和硬件测试验证了方案的正确性和可行性。In order to improve the development efficiency of DSP system, this paper introduces modem DSP technology, and has designed a QPSK modulator. According to the QPSK modulation basic principles ,the hardware model is established by using MATLAB / Simulink DSP Builder and Quartus Ⅱ. The way in the formation of the module ,using DSP Builder modules in place of VHDL programming, has the organic integration in modeling and hardware implementation on the same workbench, and then uses the Signal Compiler tool provided by the ALTERA Corporation to compile, producing the original VHDL program, meanwhile, which achieves QPSK modulation by adopting ALTERA＇s Cyclone series chip EP2C35F672C6N. Results show that the method improves design flexibility, and the correctness and feasibility of the program was verified by software emulation and hardware test.
