Abstract
In this paper, a novel widely linear minimum-mean-square-error (MMSE) anti-collision receiver for passive ultra high frequency (UHF) multi-antenna radio-frequency identification (RFID) systems is proposed. By establishing that real-world tag signals are essentially noncircular in the complex filed, the proposed widely linear estimator is proven to have better performance in recovering data from collision when compared with its linear counterpart. Simulations on tags in conflicting response is conducted, justifying the performance advantages of the proposed receiver over the conventional linear one.
