– Title: Ambient Backscatter Assisted Wireless Powered Communications
– Abstract:
Ambient backscatter communications has been introduced and quickly
become a promising choice for self-sustainable communications systems
as it does not require an external power supply and a dedicated
carrier emitter to operate. By leveraging existing RF signal
resources, ambient backscatter technology can support sustainable and
independent communications and consequently open up a whole new set of
applications that facilitate Internet-of-Things (IoT). In this talk,
we study an integration of ambient backscatter with wireless powered
communication networks (WPCNs). We first present an overview of
backscatter communication systems with an emphasis on the emerging
ambient backscatter technology. Then we propose a novel hybrid
transmitter design by employing the capacities of both ambient
backscatter and wireless powered communication. Furthermore, in the
cognitive radio environment, we introduce a multiple access scheme to
coordinate the hybrid data transmissions. The performance evaluation
shows that the hybrid transmitter outperforms traditional designs. In
addition, we discuss some open issues related to the ambient
backscatter networking.
