 通用通信信号发生器是通信系统设计、仿真和电磁环境模拟的重要要素。传统的通信信号发生器是由硬件组合构成，存在硬件规模大、成本高、不易于扩展等缺点。借鉴“软件无线电”的设计思想，利用基本硬件电路在软件编程的控制下生成通信信号的方法，提出了一种基于正交调制的信号生成器的设计方案。
Abstract:
 General communication signal generator is an important part in communication system design,emulation and electromagnetic circumstances simulation. Traditional communication signal generator which is made up hardware has many defects such as more hardware scale,higher cost and more difficult expanding.It is an important breakthrough to produce communication signals based on “software radio” design idea of which basic hardware is controlled by software.The design of general communication signal generator based on the quadrature modulation method is presented in this paper.
