On the Performance of Spectrum Sharing Backscatter Communication Systems

Spectrum-sharing backscatter communication (SSBC) systems are among the most prominent technologies for ultralow power and spectrum-efficient communications. In this article, we propose an underlay SSBC system, in which secondary network is a system. We analyze performance of under transmit adaption strategy at transmitter, guarantees that interference caused by to primary receiver below predetermined threshold. first derive novel analytical expression cumulative distribution function (CDF) instantaneous signal-to-noise ratio network. Capitalizing on obtained CDF, accurate approximate expressions ergodic capacity, effective average bit-error rate. further validate our theoretical analysis using extensive Monte Carlo simulations.
