Abstract

In the study on CoMP-JT resource allocation

it is found that the traditional ZF beam-forming precoding technology may lower the average utilization ratio of antenna transmission power under the condition of per-antenna power constraint.In order to further improve the system throughput

this paper proposes a joint precoding and power allocation algorithm

which improves the utilization ratio of antenna transmission power by using aprecoding iterative calculation method.Simulation results show that this algorithm performs much better than the traditional ZF precoding algorithm.
