The Research Of Data Format And Checkout Problem Of RFID System

RFID is a kind of auto-identify technique risen in 90'th. It is very hot in theory and application research. It has many advantages, such as abundance of data information, high security of data, great ability of anti-EMI(Electro Magnetic Interference), short recognizing time and low cost ,and it has a promising future. In this paper I first studied basic theory used in data transfer used in RFID application, including the principle of channel coding.. checkout and anti-error coding, Then I used Simulink, a powerful simulation software, designed and packed 12 models used in simulation, including channel coding, CRC, OOK etc. Then simulation and studied such topics as capability of data transfer of RFID system, channel fit ability of different channel coding etc. The research technique and research result used in this paper will offer reference for the design and application of practice application of RFID system.
