Executive Summary

In order to increase the reliability of data transmission, using multiple antennas in Radio Frequency IDentification (RFID) systems has been investigated by researchers, mainly through measurements and simulations. The Multiple Input Multiple Output (MIMO) RFID backscattering channel exhibits a special type of cascaded structure rather than that of other better-studied cascaded channels such as the keyhole fading and the double scattering fading. In this paper, the author analytically study the bit error rate performances of the MIMO RFID channel under two transmission schemes, the identical signaling transmission scheme and the Orthogonal Space - Time Coding Scheme (OSTCS).
