对铭泰读卡器不同扇区进行读写操作，初始化扇区，扇区信息加密。(Reading and Writing Mingtai Card Reader)

仿真二进制正交信号通过AWGN信道后的误比特率性能，每个信号周期取样10次，接收端采用相关器，Eb/N0的范围是0到12dB(Simulation binary quadrature signals by the bit error rate performance in an AWGN channel, each signal cycle sampled 10 times, the receiving side uses the correlation Eb/N0 is the range of from 0 to 12dB)

说明：  OFDM信号的循环谱密度，非常详细，根据协议编的，外面非常少见！(OFDM signals in cyclic spectrum density, very detailed, made under the agreement, the outside is very rare!)
