摘要

许多MIMO容量分析和预编码算法都是基于总功率约束的假设，假设功率可以在天线间自由分配。然而，在实际的MIMO系统中，每个天线的功率限制往往比总功率限制更主要的设计考虑。本文研究了具有单天线功率约束的MIMO系统的传输方案。给出了最优传输方案的充分必要条件。我们还开发了一种迭代算法，并证明了它收敛于最优解。

Optimal MIMO transmission with per-antenna power constraints

Many MIMO capacity analyses and precoding algorithms are obtained based on the assumption of total power constraint while assuming power can be allocated freely across antennas. In practical MIMO systems, however, per-antenna power constraints are often more predominant design consideration than the total power constraints. In this paper, we study the transmission schemes for MIMO systems with per-antenna power constraints. We derive the necessary and sufficient conditions for the optimal transmission scheme. We also develop an iterative algorithm and prove its convergence to the optimal solution.
