Özet

This paper investigates the performance of amplify-and-forward based one-way half-duplex (HD) and full-duplex (FD) relay-assisted dual-hop network. The investigation considers that the aforementioned system operates in sixth generation (6G) candidate bands: 4.6 GHz, 7.8 GHz, 15 GHz, and 40 GHz. The outage probability is utilized for the performance analysis. Analytical and asymptotic derivations are validated by means of Monte-Carlo simulations. The obtained results reveal that when residual loop-interference is sufficiently suppressed, FD attains slightly better outage performance than HD due to its pre-log advantage. A mild performance uptick at higher carrier frequencies stems from the frequency-dependent MT antenna gains assumed (2/3/6/10 dBi), rather than intrinsic frequency effects.
