Performance of Media-Based Modulation in Two-Way Full-Duplex Relaying Networks

Abstract

Media-based modulation (MBM) is a recently proposed modulation scheme, which conveys information using digitally controllable parasitic elements (a.k.a radio frequency mirrors) placed near the transmit antenna. In this paper, we investigate the performance of MBM in a two-way relaying network where two nodes exchange information with the help of a relay node. We consider full-duplex (FD) operation and MBM based transmission at all the nodes, and decode-and-forward protocol for relaying. We refer to the considered system as two-way FD relaying with MBM (TW-FDR-MBM) system. We introduce the TW-FDR-MBM system model and investigate its bit error performance. In particular, we carry out an average bit error probability (BEP) analysis of this system. Our performance results show that TW-FDR-MBM scheme achieves better performance compared to TW-FDR scheme that uses conventional modulation schemes like PSK/QAM.
