摘要:

提出了一种基于单天线功率约束的波束形成方法。虽然许多波束形成器的设计与PAPC需要解决复杂的优化问题,所提出的完整的功率重新分配(CPR)的方法可以生成具有优良性能的波束形成器,只有与线性操作。CPR被设计成具有简单的结构,使其具有高度的灵活性和实用性。在本文中,三个CPR的变化,考虑算法收敛速度,和速率最大化,并对信道的不确定性的鲁棒性。仿真结果验证了CPR及其变体满足其设计标准,因此,CPR可以很容易地用于各种目的。

英文摘要:

This paper proposes a beamforming method under a per-antenna power constraint (PAPC). Although many beamformer designs with the PAPC need to solve complex optimization problems, the proposed complete power reallocation (CPR) method can generate beamformers with excellent performance only with linear operations. CPR is designed to have a simple structure, making it highly flexible and practical. In this paper, three CPR variations considering algorithm convergence speed, sum-rate maximization, and robustness to channel uncertainty are developed. Simulation results verify that CPR and its variations satisfy their design criteria, and, hence, CPR can be readily utilized for various purposes.
