In this paper, we investigate the robust relay beamforming design for a multi-input multi-
output (MIMO) two-way relay networks (TWRN) by considering imperfect and reciprocal …

Most of the non-linear transceivers, which are based on Tomlinson-Harashima (TH)
precoding and have been proposed in the literature for two-way relay systems, assume …

In this paper, we study the performance of fixed decode-and-forward (DF) two-way relay
cooperative networks with multi-antenna sources employing limited feedback beamforming …

Two-way relay cooperative communication system demonstrates significant gain in spectral

We consider power control methods for two-way amplify-and-forward (AF) relay systems.
Traffics with different quality-of-service (QoS) requirements are exchanged between two …

Interference alignment (IA) is known to achieve the maximum degrees of freedom at high
SNR in interference channels, however, the reliability of IA is little discussed in literature. We …
