Opportunistic Two-Way Full-Duplex Relay Selection in Underlay Cognitive Networks.
IEEE Systems Journal（2018）
摘要
The performance of secondary user in underlay cognitive networks is analyzed by considering opportunistic selection of two-way full-duplex (FD)-based amplify-and-forward (AF) relays. The closed-form expressions for the distribution of end-to-end signal-to-noise ratio (SNR) are first derived, with independent and identically distributed (i.i.d.) Rayleigh fading channels assumed in each wireless lin...
