Relay technology is an important technical means to achieve a smooth transition from Long Term Evolution (LTE) to LTE-Advanced (LTE-A). Theoretically, the addition of nodes will improve the performance of the system effectively. While the relay is active nodes, addition of nodes become a new source of interference. Based on the LTE-A simulation platform, the effect of relay node on the system is analyzed.

Simulation Results

In this paper, we design the source precoding matrix and the relay amplifying matrix of a multiuser multiple-input multiple-output (MIMO) non-regenerative relay system. Different from the other algorithms, we first introduce a new model with new unknown but to be designed variables. Then we proposed an iterative algorithm to get the source precoding matrix and the relay amplifying matrix to optimize the system performance. The simulation results show that the proposed design algorithms can improve mean square error (MSE) performance.
