Abstract

The multiple antenna technique is one of the most promising technologies to enhance system performance to reach the challenging requirements of IMT-Advanced technical requirement ITU-R M.2134[1]. Channel state information is essential to enable closed-loop multiple antenna techniques. Channel reciprocity is an efficient and economic way of providing network with channel state information. In this paper, utilization of channel reciprocity in advanced MIMO system is discussed. Advantages and drawbacks of channel reciprocity are both discussed in detail. Simulation results are also provided to demonstrate efficiency of channel reciprocity.
