【摘要】：針對(duì)傳統(tǒng)不確定集約束穩(wěn)健波束形成算法(S-WCRB)的性能依賴于模約束參數(shù)的問題,提出了雙不確定集約束的穩(wěn)健寬帶波束形成(D-WCRB)算法.該算法將期望信號(hào)導(dǎo)向矢量約束于兩個(gè)不同參數(shù)的球形不確定集中,解決模約束參數(shù)選擇不當(dāng)引起SINR性能下降的問題,推導(dǎo)了D-WCRB算法與S-WCRB算法獲得不同SINR的必要條件,并討論了D-WCRB算法中約束參數(shù)的選擇問題.最后給出的數(shù)值仿真結(jié)果驗(yàn)證了該算法的有效性.
[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.
