摘要: 在多线性约束(MLC)最小方差准则和最大信噪比准则的基础上，提出了待定多线性约束(MLCD)最大信噪比波束形成器，确定了最优增益向量，导出了最优权矢量和最大输出信号干扰噪声比的解析表达式，与多线性约束最小方差波束形成器相比，待定多线性约束最大信噪比波束形成器具有更优越的滤波性能。Abstract: Combining the Multiple Linear Constraint (MLC)minimal variance criterion and maximal SNR criterion, the maximal SNR beamformer is proposed with Multiple Linear Constraint to Determine. (MLCD)The maximal SINR is obtained to evaluating the filtering performance. The optimal weighted vector is presented according to the optimal gain vector of desired signals. The filtering performance is improved greatly contrasting to the multiple linear constraint minimal variance beamformer.
