Abstract
In this paper, we propose regularized vector perturbation in MIMO two-way relay channels in order to align phases of received signals. The proposed scheme not only simplifies the detection process at the relay, but also removes the perturbation vector without its knowledge. Numerical results show that the proposed scheme improves the block error performance.
