摘要

This paper discusses the idea of merging massive Multiple Input Multiple Output (mMIMO) technology into backscatter radio communication systems. Specifically, we consider a passive - battery-less - Radio Frequency IDentification (RFID) system. The paper provides a mathematical framework for channel modelling of mMIMO-RFID system including the effect of large scale fading on the communication process. Furthermore, a novel beamforming scheme will be proposed which enhances the overall mMIMO-RFID system detection capability in terms of bit error rate over different interrogator ranges. The proposed idea would shift the complexity and cost to the reader side while simplifying the tag. The overall mMIMO-RFID system performance is investigated considering the case of multiple tags; each of them is equipped with a single antenna, in the interrogation zone of mMIMO based reader.
