Optimal Non-Coherent Detector for Ambient Backscatter Communication System
Optimal Non-Coherent Detector for Ambient Backscatter Communication System
The joint probability density function (pdf) of the received signal of an ambient backscatter communication system is derived, assuming that on-off keying (OOK) is performed at the tag to form non-return to zero (NRZ) line codes, and that the ambient radio frequency (RF) signal is white Gaussian. The pdf of …
