Basically, in cellular network systems, the relay station (RS) is used to increase the cell coverage of mobile stations (MS) at a cell edge. But, the system performance due to the use of RS is interfered by the neighboring cells and decreased by the low power of received signals, generally. In order to overcome these disadvantages and get a diversity gain or a high data rate, we design and propose the multiple-input multiple-output (MIMO) multi-hop relaying system structure using the BS cooperation scheme, and evaluate the performance of the proposed system in this letter. Therefore, the MSs can effectively receive the signals through the proposed design which uses the RS in the overlapping regions.
