Abstract
Space frequency block code (SFBC) based on MIMO-OFDM can obtain spatial diversity gain. However, it is limited to mobile terminal. Therefore, alternative ways have been presented based on cyclic delay or cooperative relaying. In this paper, we proposed a new approach of 2×1 SFBC-OFDM based relay cyclic delay diversity for exploiting spatial and frequency diversity simultaneously with mobile terminal having a single antenna. The proposed scheme is based on amplify-forward relay network which operates cyclical delay. The simulation results show performance improvement of the proposed scheme.
