| 摘 要： | 根据2FSK调制解调器的基本理论,采用DDS(直接数字合成)技术在不同频率信号的切换时能保持相位连续的优点来设计2FSK调制模型,采用自延迟解调法设计了2FSK的解调模型。然后利用Simulink下的DSP Builder工具箱搭建了这两个模型,并在Matlab/Simulink下对此模型进行了仿真,验证了模型的正确性。此设计可以简化2FSK调制解调器系统的硬件电路,提高系统的可靠性与灵活性,而且成本低、修改方便,对硬件理论知识要求不高,实现起来容易。

| Abstract: | According to the 2FSK modem elementary theory,using Direct Digital Synthesis(DDS) the technology when the different frequency code cut can maintain the phase continual merit to design the 2FSK modulation model,using the 2FSK demodulation model from the detention demodulation law.Then using under Simulink DSP the Builder toolbox to build these two models,and has carried on the simulation under Matlab/Simulink to this model,has confirmed the model accuracy.This design may simplify the 2FSK modem system hardware electric circuit,enhances the system the reliability and the flexibility,moreover the cost is low,the revision is convenient,is not high to the hardware theory knowledge request,realizes easily. |
