OQPSK调制在移动通信等领域应用普遍，该例程采用两类典型解调算法来具体实现，二者差别主要体现在环路滤波器设计和码元同步算法选择上，效果均可，可直接套用。建议对调制解调有兴趣的初学者细致学习之。(OQPSK modulation is widely used in mobile communications and other fields, the routine use two kinds of typical demodulation algorithm, the difference between the two is mainly reflected in loop filter design and symbol synchronization algorithm, it can be directly applied. Recommendations for modulation and demodulation of beginners interested in learning carefully.)
