对RFID读写器接收模块的解调以及FM0解码进行了MATLAB仿真。首先我们对读写器接收到的信号进行仿真，里面附带着标签信息；其次对接收到的ASK信号进行相干解调；接着解调后的信号经过抽样判决，进行FM0解码。仿真结果可表明接收到的信号与发射的信号一致。-On the RFID reader receiver module FM0 decoding and demodulation and a MATLAB simulation. First of all we readers received signal simulation, which included the tag information　followed by the received signal coherent ASK demodulation　then demodulate the signal through the sample after the verdict, for FM0 decoding. Simulation results show that the received signal and the signal line emission.
