DOI: 10.1109/lcomm.2023.3237279
Abstract: Backscatter radio only requires a simple switch, terminating the tag antenna between (at least) two loads. However, recent detection in ambient backscatter sensor networks assumes that the tag is receiver-equipped, able to synchronize its backscattering… read more here.

DOI: 10.1109/lcomm.2024.3381734
Abstract: In backscatter sensor networks, performing over-the-air computation (AirComp) is challenging, because backscatter devices are impossible to accomplish channel estimation and precoding operations to offset the distortions caused by wireless channels. In this letter, we propose… read more here.
