摘　　要：针对现有调频信道附加数据广播发送数据为目的,通过simulihk仿真软件来建立单声道调频附加信道系统仿真模型,对FM-SCA调制器、FM调制器,FM解调器和FM_SCA解调分别建模,仿真整个系统,误码率检测为0.044。得出调频附加信道进行数据广播能够传送原来单声道音频信号,同时也能进行数据广播,互不影响,扩大了FM的应用功能。In view of the existing FM channel additional data broadcast transmission of data for the purpose, to establish mono FM of subsidiary communications authorization through simulihk simulation software system simulation model, the FM-SCA modulator, a FM modulator, demodulator and demodulation of FM FM_SCA model, simulation of the whole system, the bit error rate testing of 0.044. Data broadcast to send the original mono audio signal to obtain a FM additional channel, also can carry on the data broadcast, mutual influence, and enlarges the application function of FM.
