Abstract

This paper improves a degradation of signal-to-interference plus noise (SINR) performance for the multipath interference in radio frequency identification (RFID) channel. By using a multiple input multiple output-constant modulus algorithm (MIMO-CMA), a zero-forcing (ZF) and a minimum mean square error (MMSE) criterion is resolved by the conventional CMA, supervised (S-CMA) and variable step size (VSS-CMA). Therefore, the MIMO-CMA algorithms are carried out by the computer simulation and measured data. Our results confirmed that the SINR performance can be improved by using MIMO-CMA algorithms for RFID channel as a simplicity.
