LS Channel Estimation and Signal Separation for UHF RFID Tag Collision Recovery on the Physical Layer
In a passive ultra-high frequency (UHF) radio-frequency identification (RFID) system, tag collision is generally resolved on a medium access control (MAC) layer. However, some of collided tag signals could be recovered on a physical (PHY) layer and, thus, enhance the identification efficiency of the...
