摘　　要：根据信号正交变换理论,推导了模拟调制信号和数字键控信号的离散化生成算法,基于Windows操作系统平台,采用PCI总线接口、现场可编程门阵列、数字上变频器等器件,设计实现了一种可通过软件算法灵活产生不同调制波形的射频信号发生器。通过实际信号波形和频谱例证了该方案的可行性,满足多频段、多模式射频信号产生的技术要求。The paper presented the mathematical derivation of analog modulation signal digit shift key signal discrete present algorithm according to the theory of signal orthogonal transformation. With device of PCI bus interface, Field-Programmable Gate Array（FPGA） and Digit Up-Convert（DUC）, the RF signal generator that can flexibly present different modulation waveform was designed and realized by software algorithm based on the Windows operation system. The waveform and spectrum of the actual signal prove the feasibility of this method. This technology meets the requirement of multi-band and multi-mode RF signal generation.
