【摘要】：针对传统不确定集约束稳健波束形成算法(S-WCRB)的性能依赖于模约束参数的问题,提出了双不确定集约束的稳健宽带波束形成(D-WCRB)算法.该算法将期望信号导向矢量约束于两个不同参数的球形不确定集中,解决模约束参数选择不当引起SINR性能下降的问题,推导了D-WCRB算法与S-WCRB算法获得不同SINR的必要条件,并讨论了D-WCRB算法中约束参数的选择问题.最后给出的数值仿真结果验证了该算法的有效性.
[Abstract]:Aiming at the problem that the performance of the traditional uncertain set constrained robust beamforming algorithm (S-WCRB) depends on the mode-constrained parameters, a dual-uncertain set constrained robust wideband beamforming algorithm named D-WCRB is proposed. In this algorithm, the desired signal guidance vector is restricted to two spherical uncertain sets with different parameters, which solves the problem of the poor performance of SINR caused by improper selection of mode constraint parameters. The necessary conditions for D-WCRB algorithm and S-WCRB algorithm to obtain different SINR are derived. The selection of constraint parameters in D-WCRB algorithm is also discussed. Finally, the numerical simulation results show the effectiveness of the algorithm.
