Publication number: 20120112884Abstract: The present invention relates to an apparatus and method for detecting the collision of Radio Frequency IDentification (RFID) tags. In the apparatus and method for detecting the collision of RFID tags, when a subcarrier signal from which a carrier signal has been removed by a reader ASK analog demodulation device is inputted to a baseband receiver, a peak signal for the received tag signal is generated, and useful information about the generated peak signal within a symbol section is extracted. In the case where a collision is generated because two or more tags send signals to an RFID reader at the same time when the RFID reader communicates with the tags, the RFID reader can effectively detect the collision between the tags.Type: ApplicationFiled: July 20, 2011Publication date: May 10, 2012Applicant: Electronics and Telecommunications Research InstituteInventors: Ji Hoon BAE, Kwang Soo Cho, Dong Han Lee, Man Sik Park, Chan Won Park
