Rfid backscatter type communication system

The present invention provides a backscattered radio frequency identification (RFID) communication system, and more particularly, to provide a carrier by use of the RFID reader so that the energy emitted by the RFID tag to transmit a signal back to the RF reader backscatter RFID communication system's type. Is provided a radio frequency identification inverse scattering (RFID) communication system, even in overcrowded reader environment, are not effectively perform RFID communication error is, while the RFID reader between the reader interference does not occur. Even in overcrowded reader environment, the RFID reader RF signal interference does not occur between a reader and RFID communication can be efficiently performed. When an RFID reader further steps need not synchronized to each other and receiving, making it possible to improve the compatibility of the RFID reader.
