In this paper, we consider a two-way multiple input multiple output (MIMO) Amplify-and-Forward (AF) relay system, where interference is observed at the relay node during the multiple access (MAC) phase. For such a scenario, two new joint source-relay precoding algorithms with interference suppression are proposed and their performance analyzed through simulation results. These linear minimum me...

This paper considers simultaneous wireless information and power transfer (SWIPT) for a multiple-input multipleoutput (MIMO) relay system. The relay is powered by harvesting energy from the source via time switching (TS) and utilizes the harvested energy to forward the information signal. Our aim is to maximize the rate of the system subject to the power constraints at both the source and relay...

Although multiple-input multiple-output (MIMO) is advantageous on orthogonal frequency division multiple access (OFDMA) system, it may not be possible that practical systems have more than two antennas because of size and cost. Therefore, cooperative communication has been recently proposed as a way to overcome this problem in slow fading wireless environment. However, if cooperative communicat...
