In this paper, a multi-pair amplify-and-forward (AF) massive MIMO system is investigated, where multiple source users communicate with multiple destination users via a single relay. The achievable rate of the system and its analytical expression are studied for power-scaling laws when ZFT/ZFR algorithm is adopted at the relay. The imperfect channel state information (CSI) is considered and the MMSE...
A multi-pair amplify-and-forward (AF) MIMO system is considered in this paper, in which all source users transmit their information to destination users via a shared relay. With the large N regime, the effect of small-scale fading tends to diminish while the large-scale fading plays a main role in affecting the system performance. The large-scale fading is modeled as generalized-K fading. While the...
