Fig. 9From: On the performance of cognitive full-duplex relaying under spectrum sharing constraintsPower allocation for P s and P r for three different positions of the relay: a exactly in between the secondary transmitter and destination, b near to secondary transmitter, and c near to secondary destination. Assume \(\mathcal {R} =4\) bpcu, P p =10 dB, and δ=−40 dBBack to article page
