论文摘要
这项研究提出了一种基于PSK调制的严格的每个天线功率约束，基于最小平方误差设计目标的符号级预码算法。然后以二阶锥体程序的标准形式制定了所提出的设计，从而通过内点方法实现了最佳解决方案。数值结果表明，在低和中间SNR制度的位误差方面，所提出的设计优于现有方法。
This study proposes a symbol-level precoding algorithm based on the minimum mean squared error design objective under a strict per antenna power constraint for PSK modulation. The proposed design is then formulated in the standard form of a second-order cone program, allowing for an optimal solution via the interior point method. Numerical results indicate that the proposed design is superior to the existing approaches in terms of bit-error-rate for the low and intermediate SNR regime.
