OFDMA-enabled Wi-Fi backscatter
In this paper, we for the first time demonstrate how to enable OFDMA in Wi-Fi backscatter for
capacity and concurrency enhancement. With our approach, the excitation signal is …

Laissez-faire: Fully asymmetric backscatter communication
Backscatter provides dual-benefits of energy harvesting and low-power communication,
making it attractive to a broad class of wireless sensors. But the design of a protocol that …

Fliptracer: Practical parallel decoding for backscatter communication
With parallel decoding for backscatter communication, tags are allowed to transmit
concurrently and more efficiently. Existing parallel decoding mechanisms, however, assume …
