Cooperative strategies for distributed full-duplex relay networks with limited dynamic range

In this work we study cooperative communication schemes which can benefit from a full-duplex (FD) operation. In particular, we exploit natural characteristics of satellite communication channels which allow for a full-duplex and simultaneous operation of nodes. These characteristics result in significant gains when applied to the well-known cooperative communication schemes. We start our study by defining a system of amplify-and-forward (AF) relay network where relay nodes are empowered with FD capability. We incorporate the limits of FD nodes for suppressing the inherent loopback self-interference. Afterwards we derive optimal relay selection and optimal distributed beam-forming, given the global or local channel state information. We show that optimal solutions for the aforementioned problems can be achieved in polynomial time. At the end, we evaluate the effectiveness of the proposed algorithms and the defined system compared to the half-duplex counterpart.
