Modulation diversity in two way relay channels
Mümtaz Yılmaz, Reyat Yılmaz · 2012
In this work, modulation diversity is exploited for two way relay channel through which multiple sources transmit information to each other. Under a basic framework with two sources and a single relay, a system applying modulation diversity technique together with decode-and-forward (DF) and amplify-and-forward (AF) protocols is proposed. The performance of the proposed scheme is investigated through simulation results and modulation diversity is shown to improve the performance in terms of symbol error rate for both two protocols.
