PURPOSE: A passive RFID system and method are provided to transmit a tag signal with one slot and a frequency band. CONSTITUTION: A processor(110) transits a sub channel in which collision and interference does not generate to a sleep status. A transmitting unit(120) performs the encoding of a command generated in the processor and size jitter modulation. In order that the processor grasps the sub channel by slot in which collision and interference does not generate, a receiving unit(130) performs the acquisition and demodulation of a tag signal by slot received through a plurality of sub channels. The receiving unit offers the processed tag signal to the processor. |
