为检验软件无线电平台的优越性，提出基于软件无线电的采用相干解调法解调2FSK信号的方法。根据2FSK的调制解调原理，学习Matlab/Simulink软件中的模块，并利用模块搭建模型，对各模块的参数进行设计，在软件中仿真通过，并将模型通过协同仿真生成源代码下载到软件无线电平台上。相干解调法需要载波同步，从而使解调设备相对复杂。所设计的电路经过软件仿真的信号与发送信号一致，硬件验证协同仿真后的信号与发送信号一致，证明电路工作准确可靠，达到了预期效果。
Abstract:
To test the superiority of software radio platform，a design adopTIng coherent detecTIon demodulaTIon 2FSK signal based on software radio is proposed. According to principles of modulaTIon and demodulation 2FSK，the design used Matlab/Simulink software module to structure model，set parameters of each module and simulated in the software. The model source code generated co-simulation downloaded to the software radio platform. Coherent demodulation requires synchronization，so that the demodulation devices becomes relatively complicated. The circuit design signal which is through the software simulation and the sending signal are the same， The hardware co-simulation verification signal and the sending signal is also the same. The results prove the circuit is accurate and reliable，and it can achieve the desired effect.
