中文摘要：
针对单发射节点功率约束条件下的多入单出（MISO）干扰信道，研究确保用户公平性的最大-最小信干噪比（R SIN ）优化问题。利用分层方法将原始优化问题分解为两个优化步骤，提出一种新颖的、低复杂性的单调协同波束成形算法，并验证其有效性。仿真结果表明：文中算法大约需要4次即可达到稳定点，且非常逼近穷举算法的性能。
英文摘要：
To ensure the fairness of the users,the max-min R SIN optimization problem was studied for multiple input sin-gle output （MISO）interference channel subject to per transmitter power constraint.The primal optimization problem was divided into two optimization steps by using the layered method.Finally,a novel and lower-complexity monotone coordi-nated beamforming algorithm was proposed.Numerical simulation shows the effectiveness of the proposed algorithm. Simulation results show that the proposed algorithm achieves a desirable convergence with only around 4 iterations and the performance of the proposed algorithm is very close to that of the exhaustive search algorithm.
