Summary:In this paper, we propose an ambient backscatter communication (AmBC) model with frequency diverse array (FDA), and analyze its channel capacity and detection performance. Closed form expressions for the mutual information between the receiver and the tag, the closed morphological expression and bit error rate (BER) of the AmBC using the FDA radio frequency (RF) signal source are derived. Numerical results show that the proposed AmBC using FDA signal source enhances the channel capacity and improves the BER performance, while compared with traditional phased-array (PA) AmBC communication. In addition, the effects of frequency increment, distance between the receiver and the tag together with the angle parameters on the BER are also explored.
