matlab代码 qcqp MIMO 多中继干扰网络中的分布式多流波束成形 该存储库包含用于在第 VI 节中提出的分布式联合传输和中继波束成形滤波器优化的 Matlab 代码。 来自以下论文:CM Yetis 和 RY Chang,“MIMO 多中继干扰网络中的分布式多流波束成形”,IEEE Access,第一卷。 7, pp. 7535 - 7554, Jan. 2019。可以修改代码以获得同一篇论文中提出的分布式发射波束成形滤波器优化。 抽象的 在本文中,考虑了在存在直接链路的情况下由多个放大转发 (AF) 中继辅助的干扰网络中的多流传输。 目标是在流信号与干扰加噪声比 (SINR) 约束下通过波束成形优化来最小化发射器和中继器的总功率。 对于发射波束成形优化,问题是众所周知的非凸二次约束二次规划 (QCQP),它是 NP 难以解决的。 经过半有限松弛 (SDR) 后,可以通过乘法器交替方向法 (ADMM) 算法来优化解决问题,以进行分布式实现。 解析和广泛的数值分析表明,所提出的 ADMM 解决方案收敛到最佳集中解决方案。 所提出算法的收敛速度、计算复杂度和消息交换负载优于现有解
