Multi-pair two-way massive MIMO DF relaying over Rician fading channels under imperfect CSI
Multi-pair two-way massive MIMO DF relaying over Rician fading channels under imperfect CSI
We investigate a multi-pair two-way decode-and forward relaying aided massive multiple-input multiple-output antenna system under Rician fading channels, in which multiple pairs of users exchange information through a relay station having multiple antennas. Imperfect channel state information is considered in the context of maximum-ratio processing. Closed form expressions are derived for approximating the sum spectral efficiency (SE) of the system. Moreover, we obtain the powers scaling laws at the users and the relay station to satisfy a certain SE requirement in three typical scenarios. Finally, simulations validate the accuracy of the derived results.

Abstract
We investigate a multi-pair two-way decode-and forward relaying aided massive multiple-input multiple-output antenna system under Rician fading channels, in which multiple pairs of users exchange information through a relay station having multiple antennas. Imperfect channel state information is considered in the context of maximum-ratio processing. Closed form expressions are derived for approximating the sum spectral efficiency (SE) of the system. Moreover, we obtain the powers scaling laws at the users and the relay station to satisfy a certain SE requirement in three typical scenarios. Finally, simulations validate the accuracy of the derived results.
