用MATLAB进行 rfid读写器系统仿真(Using MATLAB for system simulation rfid reader)

说明：  设计一个理想通信系统，实现信息字符流的传输。 发射器： <1>将消息（字符串形式）编码成一个符号序列； <2>用脉冲成形将串符号序列转变成模拟脉冲信号； <3>将模拟脉冲信号调制到载波信号上。 接收器： <1>对接收的信号进行采样； <2>解调信号成基带信号； <3>将信号恢复成字符串。(Design an ideal communication system, the realization information transmission of character flow. Emitters: < 1 > will news (string form) coding into a symbol sequence < 2 > by using a pulse forming will string of symbols into a simulation pulse signal sequences < 3 > will simulate the pulse signal modulation to carrier signal. Receiver: < 1 > of received signal sampling < 2 > demodulation signal into baseband signal < 3 > will signal back into a string.)

说明：  pwm整流电路，即将直流电源逆变为交流电(Rectifying circuit, will be the dc power supply inverter for alternating current)
