摘　　要：信号的调制识别技术在目前数字通信中应用极为广泛,首先介绍了OQPSK调制信号以及成型滤波器的原理,在此原理基础上给出了一种基于FPGA的OQPSK调制电路的实现方法,并用MATLAB仿真工具得到成型滤波器的仿真模型及滤波性能,在Modelsim仿真环境下对该调制实现方法进行仿真验证,得到OQPSK调制信号的波形,最后给出仿真结果,证实此OQPSK调制方法的可行性。The application of the signal modulation and recognition technology is in an extremely wide range of digital communication in the current.The theory of OQPSK modulating signal and the baseband shaping filter is introduced at first.And then,by using MATLAB,this scheme gets the simulation data of the signal shaped and analyzed the filter character.The signal waves of modulation are displayed after simulating by modelsim software.It is proved that the method of OQPSK through programming FPGA is more flexible and controllable.
