Abstract: This paper computes the secondary throughput of cognitive radio networks (CRN) where the secondary source S_S harvests power from the radio frequency (RF) signal of node A received over n_r antennas. Then, S_S controls its power to minimise the interference at the primary destination (P_D). The secondary signal is transmitted to users U_r and U_t. We show that when the number of reflectors is doubled, we obtain 15 dB gain. STAR-RIS is a good candidate for next generation of wireless communications such as 6G and beyond as it offers a large throughput.

Keywords: STAR-RIS; 6G; cognitive radio network; CRN; adaptive power.
