摘要: 在多線性約束(MLC)最小方差準(zhǔn)則和最大信噪比準(zhǔn)則的基礎(chǔ)上，提出了待定多線性約束(MLCD)最大信噪比波束形成器，確定了最優(yōu)增益向量，導(dǎo)出了最優(yōu)權(quán)矢量和最大輸出信號(hào)干擾噪聲比的解析表達(dá)式，與多線性約束最小方差波束形成器相比，待定多線性約束最大信噪比波束形成器具有更優(yōu)越的濾波性能。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.
