Abstract

In this paper we investigate wireless relay networks for two way communication over a four node Gaussian relay channel based on closed-loop extended orthogonal space time block codes (EO-STBCs) with all relays forming a distributed space time block code (D-STBC) to aid the communication between both terminals. Full data rate and full cooperative diversity can be obtained by using closed-loop D-EO-STBC. Only limited feedback information based upon channel state information (CSI) available at one of the receiving terminals is required. Simulation results based on end-to-end bit error rate (BER) illustrate that the two-way communication can achieve a good performance with simple linear processing and outperforms other two-way schemes.
