A Cooperative MIMO Mobile Multihop Relay for Cellular Networks

چکیده
In this paper, we present an analysis of mobile multihop relay (MMR) technology using cooperative multiple-input-multiple-output (MIMO) transmission. New wireless broadband protocols, such as WiMAX, and 3G-LTE apply MIMO technology, and mobile communication protocols under standardization are investigating MMR as a future technology to use. These two technologies are expected to be among the most important techniques in the near future. However conventional MIMO technology can not be applied directly in some applications. Therefore, we investigate a novel MMR scheme to which a cooperative MIMO transmission scheme can be applied. Since MMR is conducted normally for far outreaching users, one of the main factors that influence a MMR transmission scheme is the interference, which comprises of inner and outer co-channel interference (CCI). Therefore, this paper focuses on the performance analysis of the MMR scheme where the analysis is based on the signal to interference power ratio (SIR) outage probability. The results of this paper show that the CCI controlled MMR scheme can provide a performance improvement compared to the conventional MMR scheme in cellular mobile communications.

Space-shift keying (SSK) is considered for multihop multiple-input-multiple-output (MIMO) networks. In SSK, only one among ns = 2 m available transmit antennas, Here ‘m’ input bits are mapped through antenna index values.
