Abstract

We analyse the end-to-end (E2E) outage probabilities (OPs) of zero-forcing beamforming and maximal-ratio-transmission/combining (ZFB-MRT/MRC) for an underlay network, which consists of a single-antenna fixed-gain amplify-and-forward (AF) two-way relay and two multi-antenna terminals. Assuming both path loss effects and small-scale fading and considering both secondary-to-primary (S2P) and primary-to-secondary (P2S) interferences, the exact and asymptotic E2E OPs are derived.
