摘　　要：为实现全数字化、软件化和可编程化的软件无线电频率源模块,给出了一种实用的软件无线电频率源模块的FPGA实现方案.该方案利用DDS技术,使用高性能FPGA器件,基于VHDL和“兆功能”库设计,使所有过程软件化、数字化,输出信号更具有高精度、高稳定度等特点.仿真结果表明了该方案的正确性.To Implement digital and programmable frequency sources in software radio, an applied software radio frequency sources based on FPGA was presented, and the process of sin/cos and sequence signal generator was treated. Based on the hardware-describe-language of VHDL, using technology of DDS makes this designing scheme meet the high requirements of frequency sources in software radio. By simulating the sin/cos and sequence signal generator in the scheme, it proves that the designing scheme is feasible.
