摘　　要：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。借鉴"软件无线电"的设计思想,将硬件设计与电路软件编程相结合,给出了MSK调制设计方案。其中,硬件设计电路产生的最小频移键控MSK信号是后续GMSK等信号产生的基础。介绍基于正交调制的MSK调制信号设计,并利用SystemView软件进行仿真,从而为通用通信信号发生器的设计提供借鉴。General communication signal generator is an important part in communication system designation, emulation and electromagnetic circumstances simulation.Combining the hardware design and software programme,the design of MSK modulation is given.The method to generate MSK signal is the foundation of generating the follow-up GMSK signal.The design of MSK modulation based on quadraure modulation is introduced,the system is simulated by SystemView.The system design gives some reference for designation from simulation general communication signal generator.
