Introduction of Relay Station (RS) is unavoidable and wireless RS has gained more interest for next generation mobile communication systems including Wireless Broadband (WiBro) system. Also, Multi-Input Multi-Output (MIMO) scheme is an emerging technology, offering high spectral efficiency. In this paper, we propose a system architecture applying Space Time Block Coding (STBC) algorithm in RS-Base Station (BS) link and Virtual MIMO (V-MIMO) scheme in Mobile Station (MS)-RS link based on WiBro network using wireless RS. The proposed system architecture is analyzed comparing with conventional single antenna system in uplink. As a result of simulation, the proposed system architecture outperforms the 2K3dB Bit Error Rate (BER) performance in RS-BS, MS-RS, MS-RS-BS uplink. And uplink transmission capacity improved 1.7-1.8 times. The system architecture proposed in this paper, is efficient because it can improve transmission gain and system capacity without change of MS.

“…However, as demonstrated in [8]- [10], it is possible to reduce the effects of correlation without incurring a loss in multiplexing gain if there is a way to compensate for the lost spatial multiplexing gain in a different domain. In [8]- [10], compensation for the lost spatial diversity gain was achieved in the time or frequency domains.…”

In multiple antenna systems, spatial fading correlation causes a significant degradation in performance. In this work, a method for reducing the sensitivity to spatial fading correlation through the bi-directional use of spatial resources is investigated. Firstly, the concept of bi-directional use of spatial resources is introduced and the fading characteristics of the proposed bi-directional multiple-input multiple-output (B-MIMO) system are investigated. The achievable rates of the B-MIMO system are then investigated and compared with those of conventional MIMO systems for beamforming and full rank transmission. Based on those results, conditions needed for the B-MIMO system to demonstrate a larger average achievable rate are evaluated. B-MIMO systems are found to efficiently reduce the sensitivity to spatial fading correlation, while supporting comparable achievable rates in spatially white environments.
