Abstract
Various embodiments herein relate to methods and systems for backscatter communication using pre-defined templates. In accordance with at least one embodiment, there is provided a backscattering communication system, comprising a transmitting unit, a backscattering tag, and a receiving unit. The transmitting unit is configured to transmit a signal comprising a transmitted frame including a pre-defined data payload. The backscattering tag is configured to: receive, from the transmitting unit, the signal comprising the transmitted frame; encode tag data over the pre-defined data payload to generate a modified data payload; and transmit a backscattered signal comprising a backscattered frame including the modified data payload. The receiving unit is configured to: receive, from the backscattering tag, the backscattered signal; and decode the modified data payload, in the backscattered frame, to recover the tag data, wherein the decoding is based on prior knowledge of the receiving unit of the pre-defined data payload.
