The collisions in UHF passive RFID communications lie in two major categories: the reader collision and the tag

چکیده
In ISO 18000-6c passive RFID (EPCglobal Gen2) communication, a tag collision is caused when multiple tags respond to the reader simultaneously. This research proposes a means to resolve the tag collision using the well known statistical signal processing technique Independent Component Analysis (ICA) in real time as specified by the protocol. The hardware fixed point algorithm was optimized for FPGA implementation and achieved satisfactory resolution results on both stationary and moving tags.

Radio frequency identification (RFID) is a new generation of automatic identification systems, based on wireless communication technology. In these systems all the tags using one communication channel to communicate with the reader. When two or more tags transmit their data to the reader simultaneously, their transmitted signals will collide. Resolving this collision has a direct impact on the ...
متن کاملBackscattering UWB/UHF hybrid solutions for multi-reader multi-tag passive RFID systems
Ultra-wideband (UWB) technology is foreseen as a promising solution to overcome the limits of ultra-high frequency (UHF) techniques toward the development of green radio frequency identification (RFID) systems with low energy consumption and localization capabilities. While UWB techniques have been already employed for active tags, passive tags solutions are more appealing also due to their low...
