Physical Layer Security of Two‐Way Ambient Backscatter Communication Systems
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 Achieving high network traffic demand in limited spectrum resources is a technical challenge for the beyond 5G and 6G communication systems. To this end, ambient backscatter communication (AmBC) is proposed for Internet‐of‐Things (IoT), because the backscatter device (BD) can realize communication without occupying extra spectrum resources.
