Modulation Schemes in Ambient Backscatter Communication
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2017
This paper presents a low-cost backscatter system using off the-shelf components. It uses simple modulation schemes and is usable with a constant carrier as well as with ambient television signals as carrier.
The evaluation of the system shows that ranges of up to 225 m are coverable in line-of-sight environments using a constant carrier. Furthermore, it is usable with ambient TV signals with bit error rates as low as 10^−3. These results show that this backscatter system outperforms state-of-art backscatter systems.
