摘　　要：软件无线电是一种以现代通信理论为基础,以微电子技术为支撑的新的无线电通信体系结构。多速率数字信号处理是软件无线电理论中非常重要而又经常遇到的问题。文章从一个实际的应用系统出发,利用多速率数字信号处理理论构建了一个具体的内插器应用的模块,MatLab仿真及FPGA编程实现表明此内插器模块设计正确,所需硬件资源符合软件无线电实验系统的要求。该模块的设计方法及功能具有一定的实用性。Software radio is a new communication architecture based on modern communication principles and digital signal processing is very important and appears frequently in software radio. From a practical application system, an interpolator module was constructed by the principles of multirate digital signal processing. Matlab simulation and implementation with VHDL show that the design is correct ,and the demand for hardware resources meets the requirements of the software radio experimental system. The design method and the function of this interpolator module can be used in practice.
