Alamouti coding scheme for cooperative relay networks with full duplex relaying

In this paper we propose a distributed Alamouti coding scheme for cooperative network in full-duplex (FD) mode as an application of well-known Alamouti code. The proposed scheme benefits from linear decoding complexity and due to the FD mode, has increase in system rate in comparison with using half-duplex (ED) mode. The residual loop interference signal come from the relay's transmitter is added to the signal received from source in the relay's receiver. This unwanted signal because of participating several fading can be consider as a noise term in the destination. So the Alamouti code is constructed in the destination due to an acceptable approximation. Finally simulation results will approve the accuracy and capability of the proposed scheme while it is compared with previous distributed Alamouti code in ED mode.
