The number of 5G studies are increasing rapidly and various solutions that aim improved communication quality are proposed. One method that is distinguished from others is the full-duplex communication. In this study, an OFDM based full-duplex communication system is implemented in real-time by using software defined radios. In literature, there are similar studies. However, this study has an unique place due to its practical and efficient digital solution and real-time implementation. With this study, a high performing system model is demonstrated and a prototype that could provide insights for future 5G studies is implemented.
