“…If ${P}_{oi}\ge {P}_{c}$, where ${P}_{c}$ denotes the needed power by the circuit for BC, ${\mathrm{T}}_{i}$ has the ability to convey its information to D via backscattering S${}^{\prime}$ RF signals. If ${\mathrm{T}}_{i}$ is selected to reflect the signal, the effective received SNR to calculate the achievable rate at D can be written as $${\gamma}_{i}=\frac{\eta \left(1-{\beta}_{i}\right){P}_{s}{\left({h}_{i}\right)}^{2}{\left({g}_{i}\right)}^{2}}{\mathrm{\Gamma}{\sigma}^{2}},$$ where $\eta $ is the backscatter efficiency which denotes the effective RF signal reflected by the tag, and ${\sigma}^{2}$ denotes the AWGN${}^{\prime}$ power at D. The adopted modulation scheme by BC will produce a gap compared to the Shannon capacity, we use $\mathrm{normal\Gamma}$ to denote this gap in () [4].…”

“…where η is the backscatter efficiency which denotes the effective RF signal reflected by the tag, and σ 2 denotes the AWGN power at D. The adopted modulation scheme by BC will produce a gap compared to the Shannon capacity, we use to denote this gap in (2) [4]. Observing (2), it can be easily found that the higher β i , the lower received SNR at D. Thus, for T i , the value of the optimal β * i can be obtained by setting the output power just equal to the consumed power, that is, P oi = P c .…”

“…In [10], to achieve optimal ergodic capacity in the spectrum sharing system, the reection coecient of BD and the transmit power of the primary trans-mission were jointly optimized, while the BD's interference to the primary receiver is treated to be less than a predened threshold. In [11], the cooperative backscatter system with a dedicated source node is studied to split each transmission into two time slots, and such system adopted the harvest-then-transmit (HTT) protocol. Further, by optimizing the time durations of two time Slots and the reection coecient, the authors examined maximized achieved rate.…”

“…Due to the extra co-channel interference caused by the backscattered signals, the degraded performance can be reported in the above works [913]. Moreover, the backscatterassisted systems that considers how to select the appropriate working mode between the active radio or passive radio, i.e., using batteries or BC in [11,14] in terms of the outage performance and symbol error rate, respectively. Dierent from [1013], reference [15] studied a decode-and-forward (DF) enabled oneway cooperative ambient backscatter communication (CABC) system.…”
