Abstract

This poster presentation introduces a multi-subcarrier passive backscatter wireless communication which enables frequency efficient and perfectly synchronized sensor data streaming. The inevitable mutual interferences among sub-carriers are actively rejected with a sophisticated digital signal processing in the receiver. The performance of the method, in terms of the synchronization and the interference processing gain, are experimentally evaluated with two types of prototype sensors and a software defined receiver realized with USRP 2952R and LabVIEW communications. The results show that the proposed interference rejection method works both for analog and digital modulation.
