| Abstract: | RFID can be used for objects identification and assets tracing automatically and remotely by contact-less intercommunication and data changing. Along with the thorough application oi the large-scale integrated circuit and the demand of the multiple objects identification. However, the collision problem which often happens in RFID system influences the system performance badly. So the approach to solve the collision problem must be taken to improve the identification efficiency. The paper makes analysis for these algorithms in the range of high frequency and UHF. |
