Abstract :
In this paper we propose a design framework for a multi-user full-duplex (FD) relaying system, which operates with decode-and-forward (DF) protocol. Our study starts with defining a system model which encompasses the limits of a FD system to overcome its own loopback self-interference. Afterwards we present a fair design strategy for the defined system focusing on the case where perfect channel state information (CSI) is available at the relay. Furthermore, we generalize our solution to the case with erroneous CSI following the wost-case enhancement approach. In the end the proposed methods are evaluated via numerical simulations and the obtained gains are observed.
