摘　　要：介绍了超短波通信电台的低成本信号处理模块的设计方法和技巧。借助XILINX公司的低成本FPGA,采用软件无线电技术,实现了多种调制方式的中频调制解调和话音静噪功能。由于核心技术均是在一块FPGA芯片上通过硬件描述语言编程实现的,所以此种设计方法在很大程度上降低了硬件成本,也为新功能的扩充留有余地。另外,通过反复实验和使用,验证了各项技术指标均达到了电台技术要求,并且通信效果良好。The design method and techniques for low - cost signal processing module of ultrashort wave or VHF （Very High Frequency） radio are introduced. With low- cost XILINX＇s FPGA, using software radio technology, a variety of modulation of the IF（ Intermediate Frequency） modulation and demodulation and the quieting tone function are achieved. Because the core technologies are realized in an FPGA chip through hardware description language programming, this design method can reduce the hardware cost to a great extent, and is also conservative for the new function expansion. In addition, repeated experiments and application verify that the technical specifications meet the requirements of radio and the radio possesses good communication performance.
