摘要
在CoMP(协作多点发送/接收)联合传输资源分配中, 研究发现在单天线功率约束条件下, 传统的迫零波束赋形预编码技术会降低平均天线发射功率利用率。为了进一步提升系统吞吐量, 文章提出一种预编码与功率联合分配算法, 该算法采用一种预编码迭代计算方式, 提高了天线发射功率利用率。仿真结果表明, 所提算法与传统的预编码相比性能有较大提高。
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 a precoding iterative calculation method. Simulation results show that this algorithm performs much better than the traditional ZF precoding algorithm.
