Load Modulation for Backscatter Communication: Channel Capacity and Near-Capacity Schemes
Gregor Dumphart, Johannes Sager, Armin Wittneben
In backscatter communication (BC), a passive tag transmits information by just affecting an external electromagnetic field through load modulation. Thereby, the feed current of the…

The Channel Capacity of General Complex-Valued Load Modulation for Backscatter Communication
Gregor Dumphart, Johannes Sager, Armin Wittneben
This paper studies achievable information rates of backscatter communication systems where the tag performs load modulation with a freely adaptable passive termination. We find tha…
