    摘要： A method for communication in ultra-wide bandwidth RFID systems includes the steps of generating through a transceiver device an interrogation signal composed of at least a sequence of equally time spaced pulses within a period and transmitting the signal to at least one RFID identification device which generates a response signal and transmits it back to the transceiver device. The interrogation signal is coded according to a numerical coding sequence. The response signal is generated by varying, in each period of the pulse sequence of the interrogation signal, a polarity of pulses using the numerical coding sequence. An apparatus for communication in ultra-wide bandwidth RFID systems includes a transceiver device and a RFID identification device, suitable for communicating with each other. The RFID identification device includes a backscatter modulator suitable for modulating a signal reflected by an antenna of an identification device RFID.
