摘　　要：基于2FSK调制解调的原理,建立了两种不同方法实现2FSK调制的调制解调器的simulink仿真模型,并在simulink环境下进行了仿真分析。在AWGN条件下,分析了这两种调制解调方法的简易程度及平均误码率,得出结论,由自定义函数作为选频开关而产生的调制解调较经过相乘、相加而产生的调制解调系统具有一定的优越性。Based on 2FSK modulation and demodulation principle, two methods that generate modulation and demodulation of 2FSK are obtained and a simulation analysis is made in simulink software environment. In addition, an analysis of the simplicity and average error rate of the two modulation and demodulation systems with AWGN is done. It comes to the conclusion that the modulation and demodulation system generated by a function is superior to the system obtained by multiplication and addition.
