Optimal Power Allocation of MIMO Relay System under the Background of 5G
With the rapid development of mobile communication technology,5G network is excepted to be commercial around 2020 in telecom industry,but the current 5G still faces big challenges in aspects such as technical maturity,standardization,industrialization.In this paper,we start with Shannons theorem,study and analysis the air interface technology in 5G,combine the technology of mobile relay and multiple input multiple output(MIMO)to increase the coverage of wireless signals,improve spectrum efficiency and then improve the channel capacity.By establishing a mathematical model with extensibility,we analysis the network system capacity,and propose two optimization goals to meet different performance requirements of uplink and downlink phase in 5G environment.In the simplified system model,the optimization of power allocation in the uplink and downlink phase is completed by using the low complexity algorithm based on mathematical optimization.
