In this paper, we introduce a new transmit architecture that employs a 2-Dimensional Fourier Transform and a 2-Dimensional Cyclic Prefix (2D-CP) at the base station. In addition, the proposed scheme incorporates relay nodes that forward the received signals with one OFDM symbol delay. The new method introduces artificial frequency, time and spatial diversity, and unlike previously proposed relaying communication systems, the proposed scheme requires only a single transmission phase. Extensive system simulation studies have shown impressive system throughput gain compared to a single hop and conventional 2-hop systems.
