Exploiting Performance of Ambient Backscatter Systems in Presence of Hardware Impairment

In the context of ambient Backscatter systems, devices (tags and readers) transmit data by employing existing Radio Frequency (RF) signals. Most prior works consider perfect hardware impairment apply Orthogonal Multiple Access (OMA) technique, but this paper investigates case Outage Probability (OP) reduction situation when is imperfect, especially Non-Orthogonal (NOMA) technology applied. Consequently, we design a downlink transmission from base station to destination highlight different performances among users. Furthermore, indicate impact levels impairment, develop closed-form expressions OP for kinds Finally, extensive simulation results validate analysis illustrate effectiveness proposed system.
