摘　　要：对高速四相相移键控(OQPSK)调制的带通滤波器带宽选择进行了仿真研究。用Matlab仿真工具给出了OQPSK的Simulink仿真模型和相应的仿真结果,验证了奈奎斯特第一定律。研究对卫星高速OQPSK调制技术的使用有一定的参考意义。The Selection of the bandpass filter band of high speed OQPSK modulation was studied by the simulation in this paper. The simulink model of OQPSK for simulation and the simulation results were given out. The first rule of Nyquist was validated. The study was valuable to the usage and design of OQPSK modulation in the satellite communication.
